Versalis has developed new SSBRs including high vinyl functionalized types for carbon black, high and medium vinyl grades functionalized for silica, and low vinyl/low styrene grades functionalized for both silica and carbon grades, addressing most tire tread requirements for both car and truck applications.
Its Europrene SOL R X 72615 is functionalized for PC carbon black-based tread, its Europrene SOL R X 72616 is functionalized for silica-based PC treads, and its Europrene SOL R 74618 is functionalized for HP/UHP silica-based PC tread.
Versalis has also introduced structures of functionalized SSBR with very low Tg (up to -70°C) for winter silica-based PC treads, as well as for carbon black-based truck and bus treads. These grades cover a wide range of Sty %/Tg, which are based on tailored polymer macrostructures, specifically designed to enhance interaction with fillers, thus improving final tread properties.
All are already available for sampling in pilot plant quantities, and will be soon scaled up at industrial level in new expanded SSBR capacity (+ 30 kt) at a Versalis plant in Grangemouth, UK.
