Features:

wollastonite has good insulation, high whiteness, good dielectric properties and high heat-resistant and weatherproof properties.

Application:

Wollastonite is widely used in ceramics, chemical industry, metallurgy, paper making, plastics, coatings and other fields.

Wollastonite in Ceramics Application

Wollastonite can reduce the sintering temperature and shorten the firing time,achieve low-teperature fast firing,save a lot of fuel. Increase glaze luster,save cost.Improve the quality.

Wollastonite in Paints and coatings Application

Wollastonite gives the coating high cohesion,Improve mechanical strength,and resistance to cracking and weathering,.Improve the properties of coating film,such as scratch resistance,scattering,covering ability,UV resistance.

Wollastonite in Construction Application

With it's non-toxic,tasteless,non-radioactive. wollastonite is used to replace the similar building materials which are harmful to human health. It can be used in for calcium board,fireproof board ,white cement,construction putty

Wollastonite in Friction materials Application

Wollastonite can improve the stability of friction materials,reduce cracking,save cost and increase the value of the products.it can be applied to brakes pads, linings, clutch,valve plugs,pulleys and so on.
