Racine paper production and processing 65 Elk silicone paper release paper

Release paper, also known as silicone release paper, having a three-layer structure: a first layer, a paper base; a second layer, laminated; a third layer, 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. 2 Application (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. Category 3 (1) by color: A, single silicon white release paper, referring to one side is plain paper, one side is a silicone oil, more commonly used. B, yellow single silicon (blue) release paper, referring to the two faces are yellow (blue) of the release liner. (2) by weight: ranging from 35-250 grams (can be higher). (3) plus silicone oil can be divided according to whether the silicone paper and coated paper. NOTE: coated paper is only the end of paper and laminating, silicone paper if it means there are three kinds of paper. (4) by a single-sided: A, double silicon single letters, referring to one side is a silicone oil, only one side lamination, the kind of cleanliness will be increased. B, double silicon means both sides are silicone oil. C, Single silicon. D, coated paper, also known as the white plastic paper. (5) Products Material producer: A, made in China. B: imports.
