Applications

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   strength of vulcanizates, reduce the wear volume,  permanent   compression set, higher density of sulfur,improve the heat   resistance, reduce heat and improve the product heat
