Application of sericite in plastic field

Sericite, with its unique fine scale structure and silk luster, can significantly improve the optical properties of plastic products, improve the air tightness, rigidity, heat resistance and dimensional stability of plastic products when it is used as a reinforcing filler in the plastic industry, which is also the difference between sericite and other inorganic fillers.

The mechanical strength of plastic products filled with sericite has been improved to a certain extent, and the plastic will not be warped, which can give the products excellent dimensional stability; The function of shielding ultraviolet radiation, resisting infrared thermal radiation, and blocking micro electromagnetic waves; Improve the aging resistance, corrosion resistance, heat resistance, insulation and other properties of products; Reduce the combustibility, wear resistance, and permeability of the product; Improve the dielectric properties of thermosetting plastics, etc.

When 50% sericite powder is added to polypropylene, the breakdown resistance of the product is increased by 1.3 times, and the dielectric constant is increased by more than 40%. When sericite powder is used in nylon 6, it can improve the rigidity and heat resistance of nylon 6, reduce its molding shrinkage, etc. At the same time, it can also significantly reduce the production cost of nylon 6 and enhance its market competitiveness.

The properties of UPVC products with wet ground sericite powder are superior to those with common fillers such as activated calcium carbonate, calcined kaolin, talcum powder, etc. The quality is completely in line with national standards, which is also conducive to reducing production costs and improving product quality for plastic processing enterprises.
