Wollastonite for Friction Material Industry

Wollastonite needle powder is a good material for friction products. Various specifications of wollastonite needle powder with low cost and high efficiency, high quality reinforcement, for durable wheel, round brake block and lining, clutch surface and sandpaper. Wollastonite needle powder enhances durability, friction resistance, heat resistance and structural and chemical stability of these products. Wollastonite needle powder has become a good substitute for other expensive fibers. To prepare friction and brake products, asbestos is usually used as fiber. At present, many friction brake enterprises use sepiolite and wollastonite composite to replace asbestos to prepare friction and brake products successfully, and through mass production, the production rate reaches more than 99%. After trial, the product has high friction coefficient, flexible braking, low wear rate, stable performance, and because it does not contain steel fiber, does not scratch the pair, and does not produce noise, its effect reaches or exceeds asbestos based friction and braking products. It is environmentally friendly because it contains no asbestos.
