No harm

talcum powder

1. Overview.

The main ingredient of talcum powder is talc.

The main component of talc is talc-containing hydrated magnesium silicate, with the molecular formula being Mg3〔Si4O10〕(OH)2. Talc belongs to the monoclinic crystal system. Crystals are occasionally in the form of pseudohexagonal or rhombic plates. Usually in dense mass or leaf shape

, radial, and fibrous aggregates. It is colorless, transparent or white, but due to a small amount of impurities it appears light green, light yellow, light brown or even light red; the cleavage surface has a pearly luster. Hardness 1, specific gravity 2.7~2.8.

Talc has excellent physical and chemical properties such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good gloss, and strong adsorption. Since the crystal structure of talc is layered, it has a tendency to split into scales and special lubricity. If the Fe2O3 content is very high, its insulation will be reduced.

2. Application:

(1) Cosmetic grade (HZ): used for various moisturizing powders, beauty powders, talcum powders, etc.

(2) Pharmaceutical-Food Grade (YS): pharmaceutical tablets, sugar coatings, prickly heat powder and Chinese herbal medicines, food additives, isolation agents, etc.

(3) Paint grade (TL): used for white body pigments and various water-based, oil-based, resin industrial coatings, primers, protective paints, etc.

(4) Papermaking grade (ZZ): used as filler for various types of paper and paperboard, and asphalt control agent.

(5) Plastic grade (SL): used as filler for plastics such as polypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene and polyester.

(6) Rubber grade (AJ): used for rubber fillers and anti-sticking agents for rubber products.

(7) Cable grade (DL): used for cable rubber additives and cable isolators.

(8) Ceramic grade (TC): used for manufacturing electrical porcelain, radio porcelain, various industrial ceramics, building ceramics, daily-use ceramics and porcelain glazes, etc.

(9) Waterproof material grade (FS): used for waterproof membrane, waterproof coating, waterproof ointment, etc.

(10) Fine talcum powder: used in high-grade paints and coatings, plastics, cables and rubbers, cosmetics, coated paper coatings, textile lubricants, etc.
