Product Overview


Silica Powder Silicon Dioxide Amorphous Excellent Quality Precipitated Silica for Tyre, Rubber and Battery Separator  

Product Description


∞   Chemical Formula:SiO2 (White Carbon Black)

∞   CAS No:7631-86-9

∞   Feature+Application 


The product is characterized as high wear resistance and high reinforcing property. By using in tire, it can improve the cohesiveness between steel wire & cord thread and sizing material, reduce rolling resistance of tire and play an important role in enhancing the abrasive resistance and safety of tire. 


The newly-developed microsphere series of products adopt the latest pressure spray-drying technology with the features of high purity, good dispersion and environmental protection so as to future improve tear resistance and abrasion resistance of tire. 


Compared with traditional white carbon black, it more effectively improves the rolling resistance and skid resistance of tire.
