Skived PTFE Tapes, long lasting, high elongation and Pure PTFE adhesive tape
Skived PTFE Tapes, which is skived into even thin film from a cylindrical PTFE block. During the skiving, the block was fixed and rotate with a high speed, and the sharp blade will shave it into even thin film on a continuous basis.
Process of Skived PTFE Tapes manufacturing
Once the PTFE film has been skived from the PTFE(Teflon) block, it will be chemically treated or etched, which will remove the fluorine surface by creating a new sodium surface. Then the heat resistant adhesive will be allowed to bond PTFE film, resulting in Skived PTFE Tapes.
The normal adhesive including Silicone pressure sensitive adhesive and Acrylic adhesive, which can both resist high temperature.
Silicone PSA can resist heat up to +260 degrees, has high and stable adhesion, using PVC liner for protection and release, but the initial tacky is small.
However, Acrylic adhesive can resist heat up to +170 degrees, using PE liner for protection and release, the adhesion is smaller than Silicone PSA, but has much high initial tacky.
Difference of Skived PTFE Film tape and PTFE glass adhesive tape
PTFE Skived film tape and self adhesive PTFE tape can both resist heat, has non stick surface and is chemical & UV resistant. But due to PTFE skived film is 100% Pure PTFE, so the property is different.
The maximum elongation of PTFE skived film tape can be 600%, which makes it work perfect for application need flexible release sheet, such as Vacuum bagging system, cable wrapping industry and so on.
★ Longer lifetime
As Skived PTFE Tapes are 100% pure PTFE, but the PTFE content of Self adhesive PTFE fabric is limited, so the lifetime and abrasion resistant property will be different.
★ Abrasion resistant
Pure PTFE film tape has excellent smooth surface, the force of friction is lower than PTFE adhesive glass fabric. In this case, the abrasion resistant of Pure PTFE film tape will be better.
★ Dielectric strength
Skived Teflon Tape is made of 100% PTFE, however, PTFE glass adhesive fabric is PTFE coated, and combined with fiberglass. So Skived PTFE film has higher dielectric strength, and is widely used in electrical industry, such as semiconductor industry.
