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
