Release paper is also called isolation paper, anti-stick paper, silicon oil paper.
Release paper is a high-grade paper coated on one or both sides with a non-stick material. The manufacture of release paper involves two main stages, namely the lamination process and the coating process. Release paper is made from wood fibre paper and is first laminated with a polyethylene film (PE) and then coated with a thin layer of non-stick silicone. It is divided into various categories, including single-sided silicone-coated release paper and double-sided silicone-coated release paper. Due to its high resistance to adhesive materials, it provides excellent release of sticky materials such as adhesives.
Paper Release is made of paper coated with anti-adhesive substance, and its type is distinguished according to the difference of material, thickness, elongation, and single and double sides. Double-sided Paper Release; both sides are coated with silicone oil, so it is a two-sided anti-oil, moisture-proof, anti-adhesive paper products, generally used to review double-sided adhesive. Ordinary Paper Release is a three-layer structure, divided into the original paper, lamination, and release agent. The double-sided Paper Release has a five-layer structure of the original paper, two lamination, two sides coated with silicone oil, called double-sided Paper Release; there are also manufacturers require printing, production process in the original paper first printed in the lamination coated with silicone.
Anti-stick paper, also known as silicone oil paper. It consists of a three-layer structure, the first layer: base paper; the second layer: lamination: the third layer: silicone oil. It can be used in electronics, automotive foam, printing, food, medical, etc. In most cases, it is used with sticky materials, especially adhesive tapes.
In the wet production of prepreg with single-sided Paper Release, Paper Release is placed on the top and bottom of the prepreg. The lower Paper Release is attached to the prepreg as it is wound up, so the surface of the prepreg is usually protected by a layer of Paper Release. The purpose of the Paper Release is to prevent the prepreg from being contaminated and to facilitate the scribing on its surface. Another role of the single-sided Paper Release is to prevent lateral cracking of the one-way prepreg. Paper Release should meet: can stick to the prepreg, but also easy to make the two separate; does not have a chemical reaction with the resin system or contamination of the resin system; in the ambient temperature and humidity changes, the length and width of the Paper Release should remain unchanged, so as not to cause wrinkling of the Paper Release and the prepreg wrinkled; should have sufficient denseness to prevent moisture from entering the prepreg through it; the elongation of the Paper Release after being traction should be consistent with the fiber The elongation of the Paper Release should be consistent with the fiber after being traction to prevent the prepreg from being deformed or twisted due to unsynchronized drafting in the preparation process; its thickness and quality per unit area are not easy to control precisely.
