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.

Sinolam supply a simple hot stamping foil facings that HOT STAMPING FSKH(Foil-scrim-Kraft-Vinyl) Finishes, which is upgrade from FSK facing by spread hot melt adhesive on the surface of Kraft, just heat it before paste facing to glass wool or carrier. 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.
