Silicon Dioxide | Low Polymerizing and Highly Disperse Silica for Rubber | COLORCOM SICA R-LPHD Series | 7631-86-9, 14808-60-7

Short Description:

Colorcom's main silica for the rubber industry consists of five series: conventional silica (R-C), environmentally friendly dustless granule silica (R-E), easily dispersible silica (R-ED), low polymerization and highly dispersible silica (R-LPHD), and high performance silica (R-HP). They respectively have the characteristics of reducing the rolling resistance of tires, improving the anti-slip performance and steering handling performance of tires, and reducing the wear and tear of tires in order to reduce the fuel consumption of automobiles and improve driving safety.
