Asbestos, also known as "asbestos fibre", is a general term for certain silicate minerals that can be split into elastic filaments. Chemical formula: 3MgO·2SiO2·2H2O, fibrous, greenish-yellow or white, white when split into flocs, silk luster, fiber elastic, asbestos resistance to acid, alkali and heat resistance, but also a poor conductor of heat and electricity. Longer fibers used in the manufacture of fireproof textiles, such as asbestos rope, asbestos belt, asbestos cloth, etc. Shorter fibers are used in the manufacture of asbestos cement products, asbestos sound insulation materials, asbestos insulation materials (asbestos magnesium carbonate insulation powder) and low-voltage electrical insulation materials. Asbestos produces a large amount of dust in the process of exploitation and use, which damages human body in many ways

Asbestos fiber can be woven into yarn, wire, rope, cloth, roots, etc., as transmission, insulation, insulation and other parts of the material or lining material, mainly used in the building to make asbestos board, asbestos paper fire prevention board, insulation pipe and kiln mat and insulation, heat insulation, insulation, sound insulation and other materials. Asbestos fiber can be mixed with cement to make asbestos cement tile, board, roof board, asbestos pipe and other asbestos cement products. Asbestos and asphalt admixture can be made into asbestos asphalt products, such as asbestos asphalt board, cloth (asphalt felt), paper, brick and liquid asbestos paint, embedded cement pavement and expansion crack for the use of the plaster, as a senior building waterproof, thermal insulation, insulation, acid and alkali resistant materials and traffic engineering materials. Defense on asbestos and phenolic resin, polypropylene and other plastic glue, can be made into the rocket ablation resistant materials, aircraft wings, fuel tanks, rocket tail nozzle pipe and high-speed torpedo launchers, ships, cars and planes, tanks, ships persons of sound insulation, heat insulation materials, asbestos after mixed with all kinds of rubber die, still can make the liquid rocket engine fittings of sealing material. Asbestos and phenolic resin laminate can be used as thermal protection material for missile head. Blue asbestos can also be used to prevent chemical, atomic radiation of the lining, separator or filter and acid - resistant packing, rubber board.
Soft because of asbestos fiber, with insulation, heat insulation, sound insulation, high temperature resistant, acid and alkali resistance, corrosion and wear resistant properties, such as in the commercial and industrial facilities, utilities have quite a number of USES, such as fire-resistant asbestos textiles, water pipe, insulation board, such as asbestos cement products, and all kinds of insulation materials widely used in construction, electrical appliances, automobiles, household goods, etc.
