The application research of wollastonite in the rubber industry was carried out earlier in China. It can replace a large amount of titanium dioxide, clay and lithopone in light colored rubber, play a certain reinforcing role, and improve the covering ability of white colorants, playing a whitening role.
After organic modification of wollastonite, not only does its surface have lipophilicity, but also due to the double bond of the treatment agent sodium oleate molecule, it can participate in vulcanization, enhance cross-linking, and greatly improve the reinforcing effect.
