General Introduction of Asbestos Fiber:
Asbestos has the feature of high fibre strength and rapid hydrophobic speed,so it is the ideal material of asbestos-cement products. Besides, asbestos is also used widely in heat preservation products, insulation products,friction brakes, reinforcing material of of plastics,sealing gaskets, building materials, reinforcing material of asphalt pavement etc.
