Product Features:
Talc has excellent physical and chemical properties such as lubricity, anti-adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good luster, and strong adsorption. Since the crystal structure of talc is layered, it tends to split into scales and has special lubricity. If the content of Fe2O3 is very high, its insulation will be reduced.
