Application

In rubber industry, it can improve properties of white canborblack and other inorganic filler in the rubber matrix and vulanized rubber.

Modify features: reduce the viscosity of colloidal, improve mobility,increase the interaction between the filler and the raw rubber, increase reinforcing properties, improve the tensile strength and tear strengthof vulcanizates, reduce the wear volume,  permanent compression set, higher density of sulfur, improve the heat resistance, reduce heatand improve the product heat.
