Introduction of Quartz Powder

Quartz powder which is white amorphous powder and lightweight has the original particle size of less than 0.3μm, the relative density of 2.319-2.653 and the melting point of 1,750℃, forms polymer fine particles after moisture absorption, has very high insulativity, is insoluble in water and acid and soluble in caustic soda and hydrofluoric acid, is not decomposed at high temperature, and has water absorption property, chemical inertness to substrates, active ingredients and additives and good compatibility with many active ingredients frequently used in vitamins, hormones, fluorides, antibiotics, enzyme preparations and cosmetics. The quartz powder has large dispersion force in crude rubber due to porosity and large specific surface area, and has high reinforcing performance when filled in rubber.
