Mica powder in the masterbatch, the plastic in the application: 1, tensile and flexural modulus was significantly increased, planar enhance, improve dimensional stability and tensile strength, while increasing the flexural strength, reduced elongation, and enhance the toughness of the products, anti-aging, anti-crack. Engineering plastics PVC add mica powder, thermal deformation temperature of the doubling of the various mechanical properties did not decline, a slight increase in impact strength. 3, 15% nylon 66 plus mica powder, the mechanical properties decreased slightly at significantly alter the appearance of products, enhanced resistance to warped. Can significantly improve the insulation performance of the article in the base rubber. 4, reduce the thermal expansion of its filler compatibility and easy extrusion granulation and injection molding small processing equipment wear. 5, the sericite its unique two-dimensional sheet structure, the excellent performance of hardness and softness in the plastic with a wide range of uses, its excellent performance table to reduce product shrinkage and pieces, and Alice degree curvature pole small, to improve the mechanical properties of the products, heat resistance, absolute sexual and chemical stability, increase the gloss of surface of the article, to prevent the plastic aging
