  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 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   Our specification for Black crystal as follows:   Appearance: Black crystal Ash content:11.5±1.0% Sulfur Content:11.5±1.0% Volatility:2.0%max Butanone insoluble matter:52.0±3.0%     Package: 25kg/PE bag   Our production capacity: 500mt per month   Application: It is mainly used  for Tire, rubber.
