Also known as the release paper, release paper, silicone paper. Is a prepreg to prevent adhesions, but also protected from contamination prepreg release paper release paper, also known as silicone release paper, having a three-layer structure: a first layer, a paper base; a second layer, lamination; the third layer, the silicone oil. It can be used in electronics, automotive foam, printing and so on. In most cases, it is used together with a viscous material, particularly adhesive tape. [1] when wet production prepregs, prepregs are in place up and down the release paper, which release liner with the winding down of deposit attached prepreg which prepreg surface so there is usually a layer of release Paper protection. Role is to prevent the release paper prepreg contamination, but also provided for the convenience of its surface crossed. Another effect of preventing the release paper is a transverse crack unidirectional prepreg. Release paper should satisfy: can stick prepreg, yet easy to make separation of the two; chemical reaction or contamination resin system with the resin system does not occur; at ambient temperature and humidity changes, release paper length and width should be remain unchanged, in order to avoid leaving the release paper creping folds prepreg; should be sufficiently dense, it is possible to prevent moisture entering through the prepreg; after elongation by pulling the release paper fibers should consistency, to prevent the prepreg during preparation due to drawing is not synchronized to cause deformation or distortion; its thickness, mass per unit area is not easy to precisely control. Release paper made of paper coated with a release material, the model according to the material, thickness, elongation, single-sided difference and distinction. Features: (1) Glassine (bottom of glassine paper) silicone paper: high temperature, moisture, oil, generally used in food industry packaging. (2) General release paper: moisture, oil, play a role in isolation products for industry: electronics, automotive foam, printing, etc., and most of its use sticky together, particularly tape, so , the general use of the product will be used to tape release paper. (3) pvc wallpaper, PVC foam leather coating process to undertake the role. 1, cleanliness: it refers to surface clean and cleanliness, because the release paper factory production environment is different, most are not clean studio, because of cost issues, it is impossible to use clean studio, Generally He says are common plant, the better will have a lot of improvements in environmental protection and the environment, which will have an impact on cleanliness. 2, from the type of: refers to the degree of release paper from the type, at this point there is no absolute value, to see a different recipe each manufacturer to decide. 3, the peel force: refers to the time when the product is easy to tear off, of course, have strict testing standards. 1 release paper release paper Yoshikawa international companies registered specifically for the mainland in Shanghai and this point is covering the southwest and inland areas. Existing companies and offices respectively in Chengdu, Suzhou, Shanghai, Qingdao and other places. Mainly engaged in printing equipment and peripheral products, including inks, substrates, machinery, chemical products, PC, PET film and so on. Companies have professional attainments ink several decades engineers, researchers have for the printing industry is very professional process engineers, customers can set the best possible solution. One. Ink is divided into nine categories: 1. UV flexo inks, UV inks and UV waterless offset Gravure (for PP, PE and untreated PET) 2. CD VCD DVD CD-R DVD-R disc can be printed with UV ink, dye-sublimation inks and various UV screen printing, offset printing ink 3.
