Fluoride release film also known as fluorine film , its main purpose is to isolate sticky objects, such as silicone PI tape, etc. During production, storage, or transportation,It can protect the adhesive from contamination and deterioration. Currently, the most widely used carriers are tape or adhesive products.

In fact, its application principle is roughly the same as that of release membranesThe main function is to prevent adhesion, but unlike silicone oil release films, fluorine exists in the form of fluoride in the release film. Most adhesive tapes are made of a variety of substrates, including high-temperature resistant adhesive tapes（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.

Mainly used in: high-temperature adhesive, 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 membrane

1. Not prone to chemical reactions, with good temperature and humidity resistance, moisture-proof and oil-proof properties, providing product isolation;

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

3. It can prevent the adhesion of the prepreg and protect the prepreg from contamination;

4. 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.

Properties of Fluorine Release Film

1. The colors are generally transparent and milky white.

2. There is no migration phenomenon, eliminating the danger of the silicone release film transferring to the material it adheres to.

3. Controllable release force, high glossiness, high cleanliness, residual adhesion of 94%, with good surface properties.

4. Fluoride release film has good UV aging resistance, chemical corrosion resistance, and solvent penetration resistance.
