What are the principles and characteristics of fluorine release film?

The application principle of fluorine release film is similar to that of ordinary release film, mainly playing a role in anti sticking. However, there is a significant difference between it and silicone oil release film: fluorine exists in the form of fluoride in fluorine release film. Most tapes are composed of a substrate and adhesive, and there are various types of substrates for high-temperature resistant tapes, such as PET and polyimide. The temperature resistance of acrylic adhesive is inferior to that of silicone adhesive, which belongs to the same category as silicone release film. After prolonged contact, silicone adhesive is prone to various reactions, leading to adhesive tape sticking.

Fluorine release film is mainly used in the bonding scenarios of high-temperature adhesive and silicone double-sided adhesive, and performs excellently in processes such as gold finger, green adhesive, AB adhesive, 3M silicone bonding, etc. In addition, it can also be die cut into various shapes to meet special usage needs.

Fluorine release film has the following outstanding characteristics:

Chemical stability and protective performance: It is not prone to chemical reactions with other substances, has excellent temperature and moisture resistance, and also has moisture-proof and oil proof functions, providing reliable isolation protection for the product.

High temperature resistance and physical properties: It has excellent high temperature resistance, good surface smoothness, high strength, and can work stably in high temperature environments.

Pre impregnated material protection: On the one hand, it can effectively prevent pre impregnated materials from sticking, and on the other hand, it can avoid pre impregnated materials from being contaminated, ensuring the quality and performance of pre impregnated materials.

Release and sealing performance: It can firmly adhere to the prepreg, facilitate the separation of the two, and has sufficient density to effectively prevent moisture from entering the interior of the prepreg through the film layer.

Fluorine release film, with these advantages, has become an ideal choice for many high-temperature tape bonding processes, providing strong support for production and processing in various industries.
