The Eastman Impera series comprises advanced aromatic-modified aliphatic hydrocarbon resins engineered to optimize tire performance while addressing the critical trade-offs between safety, efficiency, and durability. These resins act as viscoelastic modifiers, enhancing wet grip and reducing rolling resistance by selectively adjusting the compound’s dynamic mechanical properties.
Their tailored molecular architecture ensures compatibility with natural rubber, SBR, BR, and filler systems, enabling seamless integration into existing formulations without requiring major process adjustments.
By elevating the compound’s glass transition temperature (Tg), Impera resins improve hysteresis at braking frequencies for superior wet traction.
Enhanced Traction: Improves wet-surface braking performance and road grip
Energy Efficiency: Reduces rolling resistance for better fuel economy
