Precipitated Silica Products for Rubber Applications

Precipitated silica has its roots in the rubber industry and, thanks to the increasingly sophisticated demands of end users, is more integral to rubber compounding than ever.

First associated with the U.S. rubber industry in the 1930s, PPG's precipitated silica products have been trusted for decades by manufacturers in every region of the world for their reliable performance, consistent quality and dependable global supply.

Every day, our PPG HI-SIL®, PPG AGILON®, and PPG SILENE™ silica-based performance materials are specified to fulfill the demands of rubber compounders in the Tire, Industrial Rubber, Silicone Rubber and Footwear industries.


Whether using a proven industry standard such as Hi-Sil highly dispersible silica (HDS) – or game-changing Agilon performance silica –global tire makers have relied on our reinforcing fillers for decades to redefine the boundaries of the industry’s “magic triangle.” From decreasing rolling resistance to improving treadwear and wet traction, PPG's precipitated silica products have been on the forefront of tire-performance innovation since the 1930’s.
