The most typical elastomer material utilised currently is often a styrene-butadiene copolymer. It combines the Homes of polybutadiene, that's a extremely rubbery polymer (Tg = -100 °C) owning higher hysteresis and so featuring very good wet grip Houses, Along with the Qualities of polystyrene, and that is a glassy polymer (Tg = 100 °C) having r
