The attributes of fluoride release film：

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.

Features

1. The colors are generally transparent and milky white.

2. There is no migration phenomenon, except for the danger of silicone release film transferring to the material it is tightly attached to.

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

4. It has good UV aging resistance, chemical corrosion resistance, and solvent penetration resistance.

Quality factors

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 during the second peel after the first peel. 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: Fluorine release film is a coating of silicone release agent on 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.
