Advantages of making industrial Silicone Release Paper

One side is smooth and the other is rough. To put it simply, the paper left over from the usual stickers is silicone release paper. Most of them are for industrial use, so the specifications are large, and there are also small ones, about one meter. The release paper is a kind of anti-adhesive paper, which can prevent the prepreg from sticking and protect the prepreg from contamination. When prepreg is produced by wet method, release paper is placed on the upper and lower sides of the prepreg, and as the prepreg is calendered, the lower release paper is pasted on it, so the surface of the prepreg usually has a protective layer . Release paper. The role of the release paper is to prevent the prepreg from being contaminated, and it can also provide convenience for marking the surface.

The release paper can be stuck on the prepreg, but the two are easy to separate; it will not chemically react with the resin system, and will not pollute the resin system; when the ambient temperature and humidity change, the length and width of the paper should remain unchanged. So as not to cause the paper to wrinkle and cause the prepreg to wrinkle; it has sufficient density to prevent moisture from entering the prepreg through it; the elongation of the paper after traction should be consistent with the fiber to prevent the prepreg from being out of sync during the preparation process Deformation or distortion caused by stretching; its thickness and mass per unit area are not easy to accurately control.

It is made of paper coated with anti-adhesive substance, and its model should be distinguished according to the difference of material, thickness, elongation, single-sided and double-sided. Silicone oil paper: high temperature resistant, moisture-proof, oil-proof, generally used for packaging in the food industry. Ordinary release paper: moisture-proof, oil-proof, and plays the role of product isolation. Applicable industries: electronics, automotive foam, printing, etc. Most of its application range is mainly sticky, especially adhesive tape. Therefore, it is generally used in products using adhesive tape.

1. Cleanliness. Refers to the cleanliness and cleanliness of the surface. Because the production environment of release paper manufacturers is different, most of them are not dust-free studios. Due to cost issues, it is not possible to use a clean room. Generally speaking, they are ordinary factories. There have been many improvements in environmental protection and the environment, which have had an impact on cleanliness.
2. The release degree refers to the release degree of the release paper. There is no absolute value at this point. It depends on each manufacturer's recipe.
3. Peeling force, peeling force refers to whether the product is easy to tear off. Of course, there are strict testing standards.
