This product is a kind of special material and chemical properties that make it excellent in compatibility with rubber and various additives. It becomes the best reinforcing additive in the rubber-based blend formula, which can greatly improve the performance of vulcanized rubber. It has excellent tensile and wear resistance, reduces the amount of rubber and reduces costs: it has strong affinity, giving it greater dispersion ability in raw rubber. The physical properties of silica particles are superior to carbon black in terms of reinforcing the elasticity and tear resistance of vulcanized rubber. It is a highly reinforcing filler for rubber. It is suitable as filler and reinforcing agent for various rubber products such as shoe soles, hoses, rubber rollers, conveyor belts, and silicone rubber.
