Fluoroplastic release film is made of PET as the substrate and release agent  applied to its surface. The surface of qualified fluorine release film is flat and smooth, evenly coated, and free from defects such as particles and bubbles. This product has advantages such as excellent physical and mechanical properties, small thickness tolerance, high transparency, low thermal shrinkage, and good flexibility. Suitable for high-temperature silicone pressure-sensitive tape composite die-cutting and punching, easy to peel off after use.

The application principle of fluorine plastic release film is the same as that of release film, mainly playing an anti sticking role, but unlike silicone oil release film, fluorine in fluorine plasticThe release film is present in the form of a fluoride, and most adhesive tapes are made of a variety of substrates with high temperature resistance（PET, polyimide) acrylic glue can not withstand the temperature of silica gel glue. The silica gel glue and silicone oil release film belong to the category of silycon. Over time, it will produce various reactions, that is, sticking.

The release film is mainly used for high-temperature adhesive bonding and silicone Double-sided tape bonding; For gold fingers, green glue,AB adhesive, 3M silicone bonding, etc; Die cut into any other shape for special purposes.

Characteristics of fluorine release film:

1、 Fluorine plastic release film is not prone to chemical reactions, and has good temperature and humidity resistance, moisture-proof, and oil-proof properties, playing a role in product isolation.

2、 Good high-temperature resistance, smoothness, and strength.

3、 Fluoroplastic release film can prevent adhesion of prepreg and protect prepreg from contamination.

4、 The release film can adhere to the prepreg, but it is easy to separate the two and has sufficient density to prevent water from entering the prepreg through it.
