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

Its application principle is the same as that of release films, mainly serving as an anti adhesion function. However, unlike silicone oil release films, fluorine exists in the form of a fluoride in the release film. Most tapes are made of a substrate with adhesive, which is resistant to high temperatures. There are many types of acrylic adhesive that cannot withstand the temperature of silicone adhesive. Silicone adhesive and silicone oil release films belong to the same category as Silicone, Over time, there will be various reactions that result in stickiness.

Mainly used in: high-temperature adhesive, silicone Double-sided tape bonding; Used for gold fingers, green glue, AB glue, 3M silicone bonding, etc; Die cut into any other shape for special purposes.

Features:

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 paper 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.

Factors affecting the quality of fluoride release membranes

1、 Processing environment: With the increasing progress of various products and the improvement of quality technology, the cleanliness requirements for PET release films are becoming increasingly strict, especially in the electronic film cutting industry.

2、 Residual adhesion rate: Residual adhesion rate refers to the force exerted on the release paper after the first peeling and the second peeling. The calculated data mainly reflects the curing effect of silicone oil.

3、 Peeling force: The magnitude of peeling force directly affects the performance of PET release film, and the general industry standard peeling force tolerance range is ± 15%.

       4、 Substrate: Silicone release agent is applied to the surface of PET film, and the quality of the substrate directly affects its performance. Domestic PET film substrates lag behind foreign countries in terms of thickness control and thermal shrinkage.
