Double-sided release paper

Double-sided release paper is coated with silicone oil on both sides, so it is a paper product that is oil-proof, moisture-proof and anti-stick on both sides. It is generally used to review double-sided tape.

Structure: Ordinary release paper has a three-layer structure, which is divided into base paper, coating film, and release agent. The double-sided release liner has five layers of structure: base paper, coated on both sides, and coated with silicone oil on both sides. It is called double-sided release paper. There are also manufacturers who require printing, and the production process is first printed on the base paper and coated with silicon.

Function: It is easy to understand if you know about single-sided release paper. Because it is coated with silicone oil on both sides, it is oil-proof, moisture-proof and anti-stick on both sides. If you have double-sided tape, you can take a double-sided tape and take a look at the layer of paper. The layer of paper on the double-sided tape must be double-sided release paper because the double-sided tape must be released on both sides.

Release paper supply: Our company specializes in the production of release paper and release film. You can also contact me directly, Shao Wei: you can go to Baidu to check the name.

Introduction of single-sided release paper: When the prepreg is produced by the wet method, the release paper is placed on the upper and lower sides of the prepreg, and the lower release paper is stored along with the prepreg, so the surface of the prepreg is usually There is a layer of release paper protection. The function of the release paper is to prevent the prepreg from being contaminated, and it can also provide convenience for scribing on its surface. Another function of the release paper is to prevent the lateral cracking of the unidirectional prepreg.

The release paper should meet the following requirements: it can stick to the prepreg, but it is easy to separate the two; it does not chemically react with the resin system or pollute the resin system; when the ambient temperature and humidity change, the length and width of the release paper should be Keep it unchanged, so as not to cause the release paper to wrinkle and wrinkle the prepreg; it should be dense enough to prevent moisture from entering the prepreg through it; the elongation of the release paper after being pulled should be the same as that of the fiber. Keep it consistent to prevent the prepreg from being deformed or twisted due to unsynchronized drafting during the preparation process; its thickness and mass per unit area are not easy to accurately control.

The release paper is made of paper coated with anti-sticking substances, and its model should be distinguished according to the difference in material, thickness, elongation, and single and double sides.
