Silane coupling agent can improve the grip of the tire on the wet road surface, improve its puncture and tear strength, improve the heat resistance and chipping resistance, improve the resistance to ozone aging and cracking, and improve the resistance to Abrasiveness. Features, reduce friction and heat generation, reduce rolling resistance.

Tread Compound

•  Passenger (radial) tread

Precipitated silica with the help of a coupling agent can improve wet grip and reduce rolling resistance. In oil-extended natural polybutadiene rubber tread compounds, when 14% precipitated silica was used instead of carbon black, road traction was improved by 5%, rolling resistance was reduced by 18%, and fuel consumption was reduced by 3%. The rolling resistance produced by the tread is 50% of the total rolling resistance of the tire. Since the tread compound has a great influence on the rolling resistance of the tire, it is particularly important to reduce the rolling resistance of the tread.

•  In truck tire treads

With the help of coupling agents, precipitated silica can improve its puncture and tear resistance and reduce rolling resistance. In the tread of natural rubber truck tires, 30 parts of precipitated silica is used to replace carbon black, which improves the cutting resistance and crack resistance of the tread rubber, reduces the rolling resistance by 30%, and has more obvious high dispersion precipitation Effect silica. .

• In off-road tire treads

With the help of coupling agents, silica can improve heat resistance, chip resistance and tear strength. Replacing carbon black with 10 phr precipitated silica in NR and SBR treads also significantly improved heat, chip and tear resistance.

Sidewall Rubber

In sidewall rubber, silica can improve ozone aging resistance, crack resistance and cut resistance through the action of coupling agent.
