heat sensitive vinyl foi, Hot Stamping Foil (ASKH)

Foil stamping uses heat and hot stamping foil in a specialty printing process that produces a shiny design on paper, vinyl, textiles, wood, hard plastic, leather, and other materials. Foil stamping also called hot stamping, dry stamping, foil imprinting, or leaf stamping, can be combined with dimensional embossing to make letters and images on business cards, book covers, gift cards, office folders, and a whole host of professional or personal items.

Other supplier also name it FSKV (V here means Vinyl as adhesive)
From above drawing (foil scrim kraft and hot stamping foil scrim kraft facing) we know another layer of adhesive exist in XSKH facing for heat sealing purpose.

WIKI:Tape Retention, the important index

A restricted retention period has been established to prevent permanent physical damage to magnetic tapes, especially tapes that are stored for long periods of time, such as history tapes. This provides for all magnetic tapes to be cleaned, possibly certified, and repacked at prescribed time intervals. This procedure eliminates such problems as oxide sticking, debris embedment, and edge deformation caused by tape pack shifts inside the reel. Initially, an on-site save tape retention period should be restricted to a maximum of 90 days, with only one 90-day extension. After 180 days, you should notify the user indicating that the tape should be copied (and verified) onto a recently cleaned tape, thus freeing the original tape to be tested for accuracy. The retention period for off-site tapes should initially be 180 days, with one 30-day extension.

Reflective foil insulation really stops the movement of heat. By Tim Carter

Reflective Foil Insulation

By Tim Carter ©1993-2011 Tim Carter

Summary: Reflective foil insulation really stops the movement of heat. This foil acts as a radiant barrier both in the summer and winter. The reflective barrier foil works best in the summer when the temperatures are higher.

 

DEAR TIM: Something tells me we are not going to see lower heating and cooling costs for some time. I want to lower both my winter heating bills and summer cooling bills. I have access to my attic space. Does it make sense to install some reflective foil insulation in the attic? Does one product or method work better than another? Leigh O., Tawas City, MI DEAR LEIGH: I agree with you 100 percent about the energy bills we all must pay. I can't see significant reductions on the horizon because the demand for natural gas, heating oil, propane, electricity, etc. is on the increase on a global scale. In my opinion, we all need to take this very seriously and do our best to conserve lots of energy. One way to do that is to lower the need for energy and reflective foil insulations do a superb job of minimizing both heat loss in the winter and heat gain in the summer.

Reflective foils are available in many forms and most products used in the residential and commercial marketplace are thin sheets of plastic film coated with reflective aluminum. This technology is not new by any means. If you have cooked food in advance for a meal, you probably kept the food warm by covering it with aluminum foil. As we all know, it does a superb job of bouncing the invisible infrared energy light waves back into the food. Besides your kitchen, the reflective foils operate in high-tech environments as well. For example ultra-high performance reflective foils keep astronauts alive and well inside both spacecraft and the spacesuits they wear as they float outside in outer space to repair satellites and build the huge international space station. But the reflective foils they use often employ thin films of pure gold which works far better than silver or highly polished aluminum.

 

The reflective foil products will work great in the winter months, but they perform best in the summer. As the temperature of an object goes up, the amount of radiant energy it gives off increases at a far greater rate. Remember that heat is always trying to move to a place that is cooler. For example, a roof surface that is 150F in the summer transfers much more real heat to the inside of your air conditioned house than the frigid attic gains during the winter when the house is heated to 75F. Many studies have been conducted by universities and independent government testing labs on the best way to install the reflective foil insulation products. The research appears to indicate that you want the foils as close to the heat source as possible. This means in the summer months the reflective foils work very well when stapled to the slanted underside of the roof trusses or roof rafters. It is recommended that a gap be left at both the bottom and top of the trusses so air can circulate easily on both sides of the reflective foil. These gaps allow any water vapor that seeps into the cold attic an easy escape route to the exterior of the home through roof ridge vents or via wind-powered turbine vents. You can also roll out the reflective foil directly on top of attic insulation and get a benefit in the winter and summer. If you do this, be sure the reflective foil insulation is perforated so that water vapor can escape and move towards the exterior of your home. Keep in mind that it is very important to purchase a laminated reflective foil insulation product. This means the foil is comprised of one, two or even three layers of highly-reflective foil. These layers are often separated by thin layers of plastic mesh that creates a tiny air space between the layers of reflective foil. The multi-layered products are immune from any performance loss due to dust buildup. Dust will decrease the performance of single thickness reflective foils. Be very careful about exposing these reflective foil products to direct sunlight. They are such good reflectors of radiant energy they can melt plastics or possibly start fires. If the foil is stretched tight, it is not a problem. But if the foil droops and forms a shallow bowl, the sun's rays are concentrated just as radio waves are concentrated by satellite dishes many people use for television reception. This is normally not a problem as most attic spaces rarely receive any direct sunlight. But my house is one of those rare places where sunlight can and does illuminate an attic. I have a small attic window that faces south and the winter sun streams into my attic in the middle of a sunny day. If you install a reflective foil insulation product on top of insulation, check it on cold days to see if there is any condensation on the underside of the foil. If there is a buildup of liquid water or frost, you need to increase the number and size of the perforations in the reflective foil insulation.

PET,VMPET, Mylar film and Metallized Polyester Film

1. Terms: PET, Mylar film, Polyester film.

• PET: polyethylene terephthalate;
• Mylar Film: metallized PET film with a layer of aluminum powder in vacuum environment get Mylar film；also named VMPET (Vaccum metallized PET)
• Polyester film: including not only PET film but also CPP film, OPP film and others, PET fims is the most popular one of them.

2.  Why aluminum powder in VMPET?

Silver powder, Zinc powder and other metallic powder all of them could be paint to PET, but Aluminium powder is the cheaper one with good function which made it become the most popular one, then VMPET film mainly means PET film coating with  aluminum powder.

3. what is the advantage of VMPET?

• Firstly with PET film which a kind of plastic film as substrate, VMPET could barrier moisture; 
• second with shinning aluminum powder this film could reflect light; at last price of it is acceptable.

Tack Synthetic Rubber and Other Adhesives

hot melt rubber (synthetic)

Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).

Natural rubber
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.

Acrylic
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.

Silicone
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.

Zinc oxide
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.

Kraft Paper for produce foil insulation

Brown wrapping paper is paper produced by what is called the kraft process from wood pulp. It is very strong and relatively coarse. Kraft paper is usually brown in colour. It is used for brown paper bags, wrapping, envelopes and other packaging. Kraft paper is widely available in both sheet and roll form but rolls are most commonly used.

Kraft paper is manufactured using a technique called the kraft process, kraft pulping or sulfate process and describes the technology for converting wood into wood pulp consisting of almost pure cellulose fibers. The process involves treatment of wood chips with a mixture of sodium hydroxide and sodium sulfide that break the bonds that link lignin to the cellulose. The process name is derived from German word kraft which means strength or power.

The kraft process was developed by Carl Dahl in 1879 and a pulp paper mill using this technology started in Sweden in 1890. The invention of the recovery boiler by G.H. Tomlinson in the early 1930s, was a milestone in the advancement of the kraft process. It enabled the recovery and reuse of the inorganic pulping chemicals such that a kraft mill is almost closed-cycle with respect to inorganic chemicals, apart from those used in the bleaching process. For this reason, in the 1940s, the kraft process surpassed the sulfite process as the dominant method for producing wood pulp.

Woodchips are fed into vessels called digesters that are capable of withstanding high pressures. Some digesters operate in a batch manner and some in a continuous process, such as the Kamyr digester. Digesters producing 1,000 tonnes of pulp per day and more are common with the largest producing more than 3,500 tonnes of pulp per day. Wood chips are impregnated with the cooking liquors. The cooking liquors consist of warm black liquor and white liquor. The warm black liquor is the spent cooking liquor coming from the blowing. White liquor is a mixture of sodium hydroxide and sodium sulfide, produced in the recovery process. In a continuous digester the materials are fed at a rate which allows the pulping reaction to be complete by the time the materials exit the reactor. Typically delignification requires several hours at 130 to 180 °C. Under these conditions lignin and some hemicellulose degrade to give fragments that are soluble in the strongly basic liquid. The solid pulp (about 50% by weight based on the dry wood chips) is collected and washed. At this point the pulp is quite brown and is known as brown stock. The combined liquids, known as black liquor, contain lignin fragments, carbohydrates from the breakdown of hemicellulose, sodium carbonate, sodium sulfate and other inorganic salts.

Kraft paper is nowadays not only used in roll and sheet form but also in paper bags.

aluminum foil for insulations

Description
Aluminium foil is aluminium prepared in thin metal leaves, with a thickness less than 0.2 millimetres (0.0079 in), thinner gauges down to 0.006 mm are also commonly used.[1] In the USA, foils are commonly gauged in mils. The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated to other materials such as plastics or paper to make them more useful. Aluminium foil supplanted tin foil in the mid 20th century.

Annual production of aluminium foil was approximately 800,000 tonnes (880,000 tons) in Europe[1] and 600,000 tonnes (660,000 tons) in the USA in 2003.[2] Approximately 75% of aluminium foil is used for packaging of foods, cosmetics, and chemical products, and 25% used for industrial applications (e.g. thermal insulation, cables and electronics).[2]

In North America, aluminium foil is known as aluminum foil. It is also sometimes called Reynolds wrap after Reynolds Metals, the leading manufacturer in North America. In the United Kingdom and United States it is, informally, widely called tin foil, for historical reasons. Metallised films are sometimes mistaken for aluminium foil, but are actually polymer films coated with a thin layer of aluminium.

Properties
Aluminium foils thicker than 0.025 mm (0.00098 in) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.
Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the matte finish facing out, and keep heat in with the matte finish facing inwards, the actual difference is imperceptible without instrumentation.[7] The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.[4]

Usage: Insulation
Aluminium foil is widely used for thermal insulation (barrier and reflectivity), heat exchangers (heat conduction) and cable liners (barrier and electrical conductivity). Aluminium foil's heat conductive qualities make it a common accessory in hookah smoking: a sheet of perforated aluminium foil is frequently placed between the coal and the tobacco, allowing the tobacco to be heated without coming into direct contact with the burning coal.

Sinolam Comments:

Radiant Barrier was named from the function of these commodity, means a serials of products with same function but could be totally different structure and raw materials, for example glass wool is is radiant barrier, obviously radiant barrier is just a collectively called not accurate.

In "Foil insulation“ mentioned the raw material aluminum foil which is the important part, it is more accurate than "radiant barrier" , actually foil insulation also including many kinds of laminates but all of them apply foil as raw materials, for example SINOLAM supply you aluminum foil facings which backed or faced with Kraft Paper, glass fiber fabric, woven fabric or other materials, and aluminum foil tapes which was made from facings, beside these aluminum foil composite panel which means foil backed foam (EPS, XPS) is also be took as foil insulations.

That is why we confirm the structure of products with clients once get a new inquiry.

Let draw an analogy here: radiant barrier similar food, foil insulations like roast.

What is vapor barrier?

A vapor barrier (or vapour barrier) is often used to refer to any material, typically a plastic or foil sheet that resists diffusion of moisture through wall, ceiling and floor assemblies of buildings and of packaging. Technically, many of these materials are only vapor retarders as they have varying degrees of permeability.

Materials have a moisture vapor transmission rate that is established by standard test methods. One common set of units is g/m²/day. or g/100in²/day. Permeability can be reported in perms, a measure of the rate of transfer of water vapor through a material (1.0 US perm = 1.0 grain/square-foot·hour·inch of mercury ≈ 57 SI perm = 57 ng/s·m2·Pa). Vapor retarding materials are generally categorized as impermeable (≤1 US perm, or ≤57 SI perm), semi-permeable (1-10 US perm, or 57-570 SI perm), and permeable (>10 US perm, or >570 SI perm).

Materials used as vapor retarders

Aluminum foil, 0.05 US perm (2.9 SI perm). Paper-backed aluminum.

Polyethylene plastic sheet, 4 or 6 thou (0.10 or 0.15 mm), 0.03 US perm (1.7 SI perm). Advanced Polyethylene vapor retarders that pass the ASTM E 1745 standard tests ≤0.3 US perm (17 SI perm). Asphalt-coated kraft paper, often attached to one side of fiberglass batts, 0.40 US perm (22 SI perm). Metallized film Vapor retarder paints (for the air-tight drywall system, for retrofits where finished walls and ceilings will not be replaced, or for dry basements: can break down over time due to being chemically based). Extruded polystyrene or foil-faced foam board insulation. Exterior grade plywood, 0.70 US perm (40 SI perm). Most sheet type monolithic roofing membranes. Glass and metal sheets (such as in doors and windows).

Usage

In modern construction, vapor barriers have become controversial.[1] but their use is legislated within the building code of some countries (such as the U.S., Canada, Ireland, England, Scotland & Wales). Current building science recommendations are to vary the location of the vapor retarder in the thermal envelope (exterior walls and ceiling/roof) depending on the climate zone. Some building codes require an interior vapor retarder in heating-dominated climates or an exterior vapor retarder in cooling-dominated climates. In most climates, however, it is often better to have a vapor-open building assembly, meaning that walls and roofs should be designed to dry:[2] either to the inside, the outside, or both.

Basements

In areas below foundation level (or, subgrade areas), particularly those formed in concrete, vapor retarder placement can be problematic, as moisture infiltration from capillary action can exceed water vapor movement outward through framed and insulated walls.

Under concrete slabs

A slab-on-grade or basement floor should be poured over a cross-laminated polyethylene vapor barrier over 4 inches (10 cm) of granular fill to prevent wicking of moisture from the ground and radon gas incursion.

Steel buildings

Inside a steel building, water vapor will condense whenever it comes into contact with a surface that is below the dew point temperature. Visible condensation on windowpanes and purlins that results in dripping can be somewhat mitigated with ventilation; however insulation is the preferred method of condensation prevention.

Packaging

Main articles: Package testing , Moisture vapor transmission rate, Oxygen transmission rate, and Carbon dioxide transmission rate The ability of a package to control the permeation and penetration of gasses is vital for many types of products. Tests are often conducted on the packaging materials but also on the completed packages, sometimes after being subjected to flexing, handling, vibration, or temperature.

Why You Should Use Radiant Barrier Insulation

Individuals reflective barriers that are great conductors for transferring heat via thermal radiation are known as Radiant Barrier. Heat can also be transferred through convection and conduction. But the Radiant Barrier don't guard against such methods of heat exchange.
Via thermal radiation, energy is released by every material and the extent of which is dependent on surface temperature and the relative ability of the material to emit radiation which in turn is directly proportional to heat radiated at specific wavelengths. At these provided wavelengths, the amount of energy that a substance reflects measures the Reflectivity of that material.

Emissivity of Radiant Barrier must be low (like .1 or much less) at those wavelengths at which they are supposed to function. The wavelength generally lies within mid and long infrared spectrum that is somewhere between 3 to 15 micrometers for long buildings. Reflectivity has a very fluctuating value for that Radiant Barrier. This occurs as emissivity and reflectivity never gets added to give one for varying wave length. It could be said that low thermal emissivity creates dark surfaces and for correct functioning, the Radiant Barrier should be facing open surfaces that are vacuum or air to prevent radiation.

Implementing radiant barrier
A substance was made by NASA which was reflective, light and made from plastic substrate and was aluminum coated by vapor deposition method which is commonly known as space blanket. The primary use of space blanket is to protect astronauts, spacecrafts and equipments from radiation and to retain heat as in space temperature fluctuations are common. As heat transfer in space is feasible only through radiation therefore, Radiant Barrier are much more efficient and helpful in space rather than on earth where the heat transfer can also be feasible via convection and conduction even after deploying Radiant Barrier.

Radiant Barrier may also be deployed to bring down indoor heat reduction. 
There are two methods to install Radiant Barrier provided as follows: 
1.Radiant Barrier Decking 
2.Radiant Barrier Attic Foil.

The roofs our house absorbs a lot of solar energy during sunny days. In fact the roof sheathing also gets heated up and therefore radiates heat down to attic floor. By placing a radiant barrier in the attic floor the heat is reflected keeping the top surface cool and simultaneously preventing the heat from entering the rooms. This makes a radiant barrier an efficient reflecting system. 
The conventional attic insulation and radiant barrier differ from each other. Although, they functions similarly but internally they work in a different way. The areas near a radiant barrier are cooler as it reduces the heat radiated while the traditional method of attic insulation achieves this by means of convection. This method utilizes air trapping. This technique is rated by R-value. Radiant Barrier has no R-values as they count on a lot of things.

The cost range of Radiant Barrier differs depending on a lot of factors. It depends on the shape and size as well as the requirements of the person getting them installed. Additional factors include the extra features which some individuals like to incorporate in it. The price is different for a new house and an existing one.

Therefore Radiant Barrier is very much useful systems these days. They are of vital importance and preferred these days.

Best Method for Installing a Radiant Barrier

Once you have decided to install radiant barrier, you have to determine which method of installation would suit your home best. Mainly, there are two criteria that should influence your decision:
1) The climatic conditions in your area and
2) Whether your attic has ductwork.

Two of the most common methods by which you can install radiant barrier are either stapling the attic foil to the bottom of your roof rafters or getting the radiant barrier foil insulation spread out over your existing batt or blown in attic insulation.

In case you reside in a mixed or cold climate, getting the radiant barrier installed across the attic floor insulation is the easiest and most effective. When summer comes, it would reduce radiant heat gain into the home. When it’s winter, it will lessen heat loss because of radiation and limit convective looping, which has to do with cold heavy air sinking through the attic insulation and reducing the insulation s R Value. Don t forget, foil insulation ISN T a replacement for regular attic insulation. They work in combination, decreasing both conductive as well as radiant heat flow.

If you reside in a warm or hot climate and there ISN T any ductwork in your attic, then by all means install the radiant barrier attic foil on top of your existing insulation. This happens to be the best option to minimize summer heat gain and winter heat loss. Make sure you have adequate insulation BEFORE you add radiant barrier. After you have laid out the radiant barrier over the blown in insulation, you can t put more insulation on top. This will take away the advantage you get from your radiant barrier, which requires an air space on one side of the foil to function effectively.

However, if there IS ductwork in the attic, then the staple up method is preferable. Let s look at it this way if you put ductwork in your attic, it s similar to making ice cream using the oven. By stapling the foil to the bottom of the rafters, you get the benefit of reducing radiant heat inflow into the attic insulation AS WELL AS bringing down the attic temperature. By keeping the attic temperature down, less heat will be transferred INTO the ductwork due to conductive heat flow. Additionally, it feels extremely cool when you stroll into your attic on a hot summer day and it feels much more comfortable compared to being inside an oven.

Any of the methods of installing radiant barrier works well. Where the climate is hot/warm, it s a question of what s easiest and if you have duct work. When you staple radiant barrier to the base of the roof rafters, you will get a cool attic, put the ductwork in a more favorable environment AND reduce radiant heat gain into your home. The staple up method results in the minimum overall heat gain into your home. Both of these methods of installing radiant barrier is going to make your home feel more comfy and save you money on your utility bills.

Environment Protection, Energy Saving and Thermal Insulation

Natural disasters took place and caused the severe damage, more and
more people have realized environment protection is a very important
thing and human beings should do something to for example save energy,
reduce electricity consumption, ride bicycle to office instead of
drive car, all these will be helpful to protect earth, and one of the
most important and effective method is taking thermal insulation in
resident and commercial buildings.

Radiant Barrier Foil Insulated Materials which was made from single
and multilayered aluminum foil with backing materials like Kraft,
fibrous cloth, woven cloth, give us variety of insulations could be
installed as roof sheet, wall covering for reflect radiant in summer
and block energy emission in winter.

Sinolam design and produce different laminated heat insulations
according to environment and requirement from clients. For example
foil woven insulation is very tough could endure hihg tensile
strength; perforated foil is breathable allows moisture move out and
foil glass fiber fabric insulation will not rot because all raw
materials taken to produce it are inorganic matter.

Not only for the purpose to protect environment by apply foil
insulaiton jackets, but also will help people save life cost.

Industry trends of foil insulation

With manufacturers of Reflective Foil Insulation in China become more and more, good things happened to this industry beside profit become lower and  lower

1. Producers of foil insulation start to value the function of international Certification, e.g. ISO, SGS, ASTM;

2. More and more honest suppliers of reflective foil develop oversea market with top quality products and professional service;

3. Manufacturers and suppliers of laminated foil are trying to extend the application beyond the traditional usage radiant barrier and vapor barrier as accessory of glass wool / rock wool and mineral wool in roof insulation, wall insulation, loft / attic insulation, for example SINOLAM offer a breathable foil insulation Jacketings which was punched get micro-holes in it, this will help vapor / moisture emission out; another sample is SINOLAM are study a new small piece laminates which could be put between cement and meanwhile will not influence it robustness, and various foil tape was developed as the requirement of market.

All in all buyers from oversea will get more and more benefits, but still should be aware of the quality of raw materials besides fraud sellers.
