Talc is a kind of magnesium silicate mineral, with its unique dry sliding property, low hardness and high melting point, good insulation for electricity and heat, low expansion and contraction force, high dispersion, strong hiding power. , good oil absorption and hydrophobicity. Slippage, small coefficient of friction, chemical stability. Acid and alkali resistance. Because of its stable chemical properties, it is widely used in paper, chemical, paint, ceramic, cable, rubber and other industrial sectors.
Talc powder is used to improve the processing performance of the rubber plastic resin such as compression molding, calendering, extrusion, injection, etc., and the replaceable part is more expensive (rubber) 10 to 15% to reduce raw material costs and provide physical properties in the paint, coating , Anti-exposure, high temperature resistance, no discoloration under ultraviolet light irradiation, long-term maintenance of the original luster and color, good resistance to acid and alkali corrosion, and good water resistance, anti-pollution, anti-aging properties, Wear resistance, steam resistance and strong flame retardancy

The use of talcum powder is very extensive. The largest volume of automotive precision plastic mold projects is the paper industry, followed by the waterproof material industry.
Paper industry
Talc is mainly used in the paper industry for three purposes, namely as a resin control agent for fillers, coatings and pulps. Talc makes the paper strong and white, increases the opacity and brightness, and enhances the ability to absorb ink. Talc has a strong fixation on pigments, giving color prints good color results.
The talc's concave abrasion value is very low, and it causes little wear on papermaking equipment and printing equipment. Furthermore, talc has a lower density than titanium dioxide (TiO2) and therefore is superior to titanium dioxide as a filler. The price of talc is much lower than titanium dioxide, making it more competitive.
Talc has been successfully used in the deinking process of waste paper, which can effectively deink the waste paper in flotation and washing.
waterproof material
Talc can be used as a filler for roofing products such as linoleum, roofing paper, asphalt shingles, roofing panels, etc., and can also be used as an anti-adhesive powder for roofing materials. When used as a filler, talc acts as a stabilizing agent in the bituminous component that melts in the injection molding recruitment information and increases the stability and weathering resistance of the roofing material. When talc is sprayed on the surface of asphalt shingles or rolled roofing materials, it can be prevented from sticking during manufacture and storage. The waterproof material industry can use low-grade colored and imperfect coarse-grinding talc.
Other industries
Talc has important applications in the plastics industry, rubber industry, cable industry, ceramic industry, paint industry and textile industry.
