ZENYESIL^®21 series is high performance precipitated silica, which adopts leading new technology to achieve much bigger effective specific surface area. It strengthens the combination of silica and rubber compound in the mixing process, and further increase the wear resistance of the rubber compound. Besides, compared with other silica withsame specific surface area, ZENYESIL^®21 series can reduce heat generation greatly during the mixing process.

ZENYESIL^®13 series precipitated silica is highly dispersible silica, to meet the“green tire” requirement, it improve the dispersion in the filler on the basis of ZENYESIL^®3 series to achieve efficient mixing, especially fit for tire tread which requires high abrasion resistance, low rolling resistance and excellent wet grip.

ZENYESIL^®3 Series precipitated silica is easily dispersible silica with strong reinforcing property in rubber, widely used in tires, footwear and other rubber products. Our products could be provided in three different forms, powder, micro-pearl, and granular.
