Factory direct sales of ultrafine talcum powder 325-8000 mesh

talcum powder

800 mesh

feature

Grinding with natural talc, the product can activate surfactants according to user requirements. Good suspension, good adsorption and affinity, good processing fluidity when applying EVA slippers, sandals, foam and other products with space and separation function (skeleton). It not only has excellent reinforcing properties, but also enhances the wear resistance of products and prevents fission.
Hard plastic can improve product filling, dimensional stability, and lubricity; in order to prevent high-temperature creep and reduce molding machine wear, the hardness of the filled polymer is increased, and the creep resistance and impact strength are basically the same. If handled properly, it can improve the thermal shock resistance of polymers, improve the molding shrinkage of plastics, and increase the flexural modulus of elasticity and tensile yield strength of products.
