Characteristics of smooth sheet: (1) there are two types of internal injection type and coating type, internal injection type is through the addition of reagents to make the surface of the sheet factor increased to large enough to achieve the effect, coating type is in the surface of the sheet to add a surfactant to make the surface smooth; (2) the friction coefficient between the sheet and the sheet or other objects to reduce, reduce the damage to the original very bright surface; (3) good demoulding, separation effect, and quite even, the surface is not greasy, do not produce other bad results; (4) does not contain silicon.   USES: (1) the built-in slider for thin and surface requirements of the flat film or cover; (2) built-in smooth sheet material is especially conducive to surface printing needs; (3) used for the separation of thin sheet products; (4) for the surface requirements of high blister sheet, tray is not easy to scratch; It is used for series of products that can not spray mold release agent and surface printing and has good adhesion.
