Applications

OSi HIOSil STEPO Silane, a thiocarboxylate functional silane, has been shown to enable reduced rolling resistance without loss of wet traction while increasing overall production efficiency for tire manufacturers as compared to standard sulfur silanes.

• Improved Payne Effect 

• Increased resilience

• Reduced Tan δ  

• Excellent dynamic properties at low temperatures (-20°C to +10°C) 

• Better wet traction

• More efficient manufacturing
