High purity, good fluidity, and uniform particle size, can be used in the rubber industry to improve the tensile strength of rubber, improve tear resistance, increase wear resistance and so on.
· The reinforcing property is close to carbon black, giving rubber products light color and transparency.
·Improve the tensile and wear resistance of vulcanized rubber, reduce the consumption and cost of rubber
·Strong affinity and covering power in raw rubber
·Improve the mechanical strength and tear strength of vulcanized rubber, which is a high reinforcing filler of rubber
