Role of Wollastonite in Rubber

High tensile strength, high elongation at break, high tear resistance, excellent wear resistance, improved electrical and thermal insulation, excellent Shore A hardness, excellent UV stability, reduced compression deformation, improved temperature resistance, excellent smoke and fire suppression, reduced or eliminated gas volatilization, odorless, low linear expansion coefficient, low permeability, excellent weather resistance.

In light colored rubber, it can largely replace titanium dioxide, clay and lithopone, playing a certain reinforcing role, and can improve the covering ability of white colorant to improve the whitening effect;

The organic modified wollastonite filled in SBR can improve its tensile strength, tear strength, elongation at break, wear resistance and other properties;

The surface of the surface modified wollastonite powder is lipophilic, which improves its wetting and dispersion properties in non-polar styrene butadiene rubber. At the same time, because the sodium oleate molecule of the treatment agent has double bonds, it can participate in vulcanization, enhance cross-linking, and greatly improve the reinforcement effect.
