HK-111R Rubber Type Wollastonite Powder (Class I)

Applications:

Specific wollastonite powder can be used to be the substitute for lithopone, part of titanium dioxide, white carbon black, light calcium and clay in different finished rubber products.

The application results show that wollastonite can improve the covering ability of white colorant and play a role in whitening.It can replace a large quantity of titanium dioxide, clay and lithopone in the adhesives with light colors, which can strengthen the qualities of the products and reduce the cost.The combination of wollastonite and coupling agents can improve the properties of rubber compounds and expand its application range.
