Silicon free release film is a special type of release film that differs from ordinary silicon release films. The surface coating layer is not commonly used as a siloxane component, but is coated with a fluoride without siliconThe surface of PET film achieves the effect of release.

It is a high-performance and environmentally friendly release film, made from modified high-temperature resistant polyester film as the raw material. After formula optimization, lubricating materials are added to the raw material to form the film. This silicon free release film has certain peel characteristics during the high-temperature and high-pressure lamination process. similarThe TPX material is the same,The surface of the silicon free release film is not coated with any release substances that are prone to residue, and it relies entirely on the release ability of the film itself to peel off the soft board, so it will not contaminateFPC board surface has the characteristics of environmental protection, no residue, strong temperature resistance, good mechanical strength, and high dimensional stability. It is widely used in fields such as printed circuit boards, FPC flexible circuit boards, electronic and electrical, printing and packaging, pharmaceuticals, and tape adhesive.

Performance 

1. There is no transfer situation, and the risk of the silicone resin release membrane migrating to the material next to it has been eliminated;

2. The error value of the net weight per unit area of one or both coatings on the release film is very small;

3. The base film has excellent impact toughness and organic chemical properties;

4. It has high reliability under extreme standard temperatures, with a heat resistance of around 130 ℃ for a long time and around 180 ℃ within an hour;

5. Long storage life;

6. Adhesive release PET can be divided into light release type, medium release type, and heavy release type based on the migration of silicon and the transformation of the release force after heating. The release force can be controlled according to demand, and the high-temperature resistance performance is excellent.
