Buna® FX 3211

This product is a functionalized Styrene-Butadiene Rubber containing 32 wt. % of vinyl, 11 wt. % of bound styrene and 5 phr of TDAE extender oil. The functionalization increases the interaction with fillers such as silica and carbon black resulting in reduced hysteresis / rolling resistance in tire compounds and improved wear resistance. Typical applications are silica and carbon black filled winter- and all-season tread compounds as well as truck and bus tread compounds.
