The role of mica powder in rubber and plastic materials?
Sericite can do all kinds of rubber products, lubricants, release agents, hygroscopic agent, anti corrosion, anti cracking, anti aging products high temperature shrinkage, can make the product quality performance is greatly improved, the heat is carbon black is excellent.
In the rubber surface and sericite powder to prevent rubber adhesion each other has a good effect, sericite in rubber can replace kaolin clay, calcium carbonate, etc.. Sericite is used in transparent rubber sole instead of white carbon black. Sericite is a mineral filler that combines various functional properties.
Can be used in polyethylene, nylon, polyester, ABS and other hot plastics, as well as phenolic resin, epoxy tree fat and other hot gene plastics, as well as thermal gene plastics filling agent, and even can make oil drums. The breakdown voltage of polypropylene with a weight of 50% is increased from 20 thousand V / mm to 46 thousand V / mm in polypropylene. The amount of Sericite in resin is usually 10%~40%, and the fineness is 800-1250 mesh. The softening point of the mechanical strength of the utility model can be increased so that the utility model has the advantages of higher strength, abrasion resistance, heat resistance, and enhanced corrosion resistance, and the production cost is greatly reduced.
