Talc powder is a kind of industrial raw material of magnesium silicate minerals. After the natural talc ore (raw material of talc powder) is sorted according to the purity grade, it is directly crushed into different fineness by crushing equipment. The commonly used fineness is 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1250 mesh to 8000 mesh. Usually, it is packed in woven bags and composite paper bags (20kg/25kg specifications). Talc has low hardness, and has physical and chemical properties such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good luster, and strong adsorption. Talc powder is mainly used in plastics, rubber, paper making, paint and coating, chemical filler and rubber products anti sticking agent and other industries。
