2.Application and advantage :

Application: Wollastonite can be widely used in construction field, brake linning, insulation field etc.

wollastonite fiber, especially dedicated to high-end friction materials, can greatly increases wear and heat resistance of friction materials by its acicular shape and unique physical property. The frictional flexibility and stability of friction materials can be improved when filled up by wollastonite fibrous products.

Wollastonite can substitute asbestos in friction and braking field as friction coefficient increases when wollastonite is added into friction materials. In this case, brake flexibility improves, wear rate decreases, and performance is stabilized without creating noise or scratching dual. At the same time, being innocuous and harmless, wollastonite is environmentally protective.
