Polyisoprene (IR)

Polyisoprene (IR)

SKI-3, 3-S, and rubber SKI-3 are a substitute for natural rubber. They can be used independently or in combination with other rubber, for the manufacture of tires, footwear and a multitude of rubber-technical commodities. The benefits of compounding with synthetic natural rubber include consistency, low impurities, improved manufacturability and cost.


Polyisoprene rubber has good resilience, low hysteresis, low rolling resistance and high fatigue resistance. Polyisoprenes also have excellent tensile strength characteristics and are operable in low temperature -65ºF (-54ºC) environments.
