Talcum powder is widely used in various industries, talcum powder according to the size of its crushing granularity, is divided into two types of finely ground talcum powder and micro fine talcum powder. The finely ground talcum powder is divided into 9 varieties according to different industrial uses.

Paint grade talc is used for white body pigments and all kinds of water-based, oil-based, industrial coatings, primers, protective paints, etc. Paper grade talc is used as filler for all kinds of paper and cardboard, wood asphalt control Plastic grade talc is used for polypropylene, nylon, PVC, polyethylene, polystyrene and polyester, etc., plastic fillers Rubber grade talc is used for rubber fillers and anti-sticking rubber products Cable grade talc is used as cable rubber reinforcement, cable separator, ceramic grade talc is used as cable rubber reinforcement and cable separator. Ceramic grade talc used for manufacturing electric porcelain, radio porcelain, industrial ceramics, building ceramics, ceramics and ceramic glaze, etc. Waterproof material grade talc used for waterproofing membrane, waterproof coatings, waterproof ointment, etc. Micro talc paint coatings, plastics, cables, rubber, cosmetics, coated paper, textile lubricants of various varieties of talc according to the physical and chemical properties of talcum powder is divided into three quality levels of excellent, first-class products, qualified products. The quality of talcum powder is divided into three grades: excellent, first class and qualified.

Classification of talc specifications, finely ground talcum powder according to its fineness and sieve through the rate, divided into the following two specifications:

a. Fineness 45μm, expressed as the weight percentage of the product passing through the sieve.

b. Fineness 75μm, expressed as the weight percentage of the product passing through the sieve.

Fine talcum powder according to its particle size distribution and particle size composition, to less than 20, 10, 5, 2μm of the cumulative percentage of the product expressed.
