basic feature

Talc has excellent physical and chemical properties, such as lubricity, anti-sticking, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good luster and strong adsorption. Because the crystal structure of talc is layered, it tends to split into scales easily and has special lubricity. If the content of Fe 2O 3 is high, its insulation will be reduced.
