Talc is a water-containing layered silicate mineral with the chemical formula 3MgO•4SiO2•H2O. Talc powder has good chemical stability, strong acid and alkali resistance, but also has good electrical insulation properties and heat resistance. As an excellent functional raw material and filler, it can be used in plastics. Modification can change the surface affinity of talc powder, so that plastic and talC better combination.

With the continuous improvement of society on mining, impurity removal and production processes, transparent inorganic fillers are now slowly entering the filler market, playing a significant role in coatings, modified plastics and other industries.
