Acicular Wollastonite Powder
Application in Friction Materials
Description
Wollastonite can
improve the stability of friction materials and decrease or solve the cracking problems,which significantly strengthens the friction resistance, heat resistance and other physical and mechanical
properties of the finished products.
Wollastonite
can also partly or totally be an alternative to other fiber raw
materials in friction materials to reduce the cost and enhance the added values.
In
the production of ceramic bonded abrasives and grinding wheels, wollastonite can greatly improve the melting speed and high temperature shock resistance.
