Buna® VSL 4526-2

Buna® VSL 4526-2 is a solution Styrene-Butadiene Rubber containing 26% of bounded styrene. The extension with 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 4526-2 has a modified microstructure with a high vinyl content. The high vinyl content increases the Tg values which result 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 is enhanced.
