Buna® VSL 2438-2

Buna® VSL 2438-2 is a solution Styrene-Butadiene Rubber containing 38% of bounded styrene. The high Mooney viscosity and extension with 37,5 phr TDAE extender oil allows for very high molecular weights in the rubber increasing the treadwear resistance combined with easy processing. Buna® VSL 2438-2 has a modified microstructure and high styrene content. The increased Tg value results in an excellent balance of important properties in tire compounds like handling, traction and rolling resistance. Corresponding vulcanizates have excellent resistance to reversion and a distinguished resilience, while keeping flexibility at relatively low temperatures. Typical applications are high performance tire treads. Important tire properties like grip and rolling resistance are enhanced.
