Talc powder for the plastic and extrusion industry is an excellent filler due to its blending characteristics, thermal and electrical resistance. Moreover, talcum powder for the plastic filler is chemically inert and provides a smooth feel to the plastic surface.
Talc is a magnesium silicate mineral belonging to the trioctahedral mineral. The talc is generally in the form of block, blade, fiber or radial, and has a slippery hand. It has the characteristics of small hardness and high melting point. Talc powder has good insulation for electricity and heat, low expansion and contraction force, high dispersibility, strong hiding power, good oil absorption and hydrophobicity, large slipperiness, small friction coefficient, stable chemical properties, acid and alkali corrosion resistance.
Due to its stable chemical properties, it is widely used in paper, chemical, paint, ceramics, cable, rubber and other industries.
