Features

&: Granular silica to protect environment, reducing powder dust, easily transfer, high mixing speed, no dusty, no bubble, obviously to improve compound rubber performance.
&: With particular physical and chemical properties.
&: Widely used as reinforcing additive of compound rubber
&: Improving tensile strength and abrasive resistance of vulcanized rubber.
&: Better enhancer on the mechanical strength and tearing force of vulcanized rubber than carbon black.
&: Reducing the rubber dosage to lead whole cost reduction.
&: High dispersion ability in compound rubber
