Modified talc powder

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 have space and a separating function (skeleton), has good adsorption and affinity, processing good fluidity, and both reinforcing performance excellence, enhanced wear resistance and prevent the fission products.
Plastic filling can improve the rigidity, dimensional stability, lubricity; can prevent the high temperature creep, reduce the abrasion of molding machine, the polymer can improve the hardness and by filling in the creep resistance and impact strength basically unchanged. 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.
