Talc
Natural talc grinding, products can be based on user requirements of the activation of the surface activator. Good suspension, in the application of EVA slippers, sandals, foam and other products with space and a separating function (skeleton), has good adsorption and affinity, processing good fluidity. It not only has excellent reinforcing performance, enhance the wear resistance products and prevent fission.
Rigid plastic can improve product filling, dimensional stability, lubricity; to prevent the high temperature creep, reduce the molding machinery wear, the polymer filled with increased hardness and creep resistance and impact strength is essentially the same. If handled properly, the heat shock resistance of the polymer can be improved, the molding shrinkage of the plastic is improved, and the bending elastic modulus and the tensile yield strength of the product are improved.
