PPG Silica Products for the Tire Industry

Adding improved performance and increased structural integrity to tires for every type of vehicle, both on and off the road, PPG offers a full line of precipitated silicas designed specifically for tire applications.

Our Hi-Sil™ and Ciptane™ silicas are used to alter the properties of the tread compound, usually in combination with silane coupling agents, to improve rolling resistance, wet traction and other dynamic properties. Our products are also used to promote adhesion to brass coated wire and fabric cord, to alter stiffness in the bead area, and to reduce the tendency for "chunk out" of off-road tire treads.

Hi-Sil™ Performance Benefits

Traction / Rolling Resistance - Alter the dynamic properties of the tread compound, usually in combination with appropriate polymers and silane coupling agents, for increased traction and/or reduced rolling resistance (better fuel economy) in high performance passenger tires
Adhesion - Increase adhesion to brass-coated wire and fabric cord, alone or as part of a bonding system, to improve composite adhesive properties of various tire components such as the steel belt, belt edge, carass plies, and bead insulation
Stiffness - Alter stiffness in the bead area for improved sealing and in the lower sidewall for more responsive handling
Tear Resistance - Improves compound tear resistance, reducing the tendency for "chunk out" of off-road tire treads
