Fluoride release film is made of fluorinated organic silicon coated on the surface and has the characteristic of high temperature resistance. Regarding silicone tape, it has excellent peeling function. Fluorine release film is primarily used in high-temperature tape and gold finger composite die-cutting processes.

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

nature

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%, fluorine release film with good surface properties.

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

During the die-cutting process, the release film usually encounters the following problems

1： After the adhesive tape and release film bonding machine are released, some of the adhesive tape is released and transmitted.

Reason: When getting rid of it, there is a sound, which is initially caused by the excessive release force of the release film, followed by uneven glue adjustment.

2： Causing anti elimination, the raw materials that should be eliminated have not been eliminated

Reason: Direct cause of anti escapeThe irrational combination of release force of PET release film is caused. Due to the unqualified original inspection of the release film, incomplete inspection machinery and equipment, and unstable production process, the release force of this specification and model of release film will be uneven and the voltage will be quite high.

3： After punching and placing for a period of time, the release film and adhesive tape cannot be removed

Reason: After placement, the adhesive tape and release film cannot be removed, which is usually due to uneven glue mixing. In some areas, the release force is insufficient, causing the adhesive tape to be unable to be removed.

4： The release film causes Electrostatic induction during unwinding and rewinding, leading to dust adsorption

Reason: It was not carried out in a clean workshop. To solve the dust problem, one can equip a clean workshop for production and processing, and the other is to use anti-static materialsPET release film raw material.

How to use it together

Fluorine release films can be used in combination with silica gel because silica gel and silica release films are prone to chemical reactions, while fluorine can effectively isolate silica gel molecules.

The silicon release film is generally used with acrylic adhesive, which can play a good role in penetrating the molecules of the isolation adhesive, and can easily peel off the double-sided tape from the release film.

1. When the single piece adhesive of a single die cutting product is less than 10mm, the ratio of release film release force should be increased.

2. The function of release film is to isolate the molecular penetration of Double-sided tape and generate release force, but the thicker the Double-sided tape coating is, the greater the fluidity of adhesive is, and the stability of release force combination will be relatively low, so the ratio of release film should also be increased.
