THE PARKING HEATER DIARIES

The commonest elastomer content utilized now can be a styrene-butadiene copolymer. It combines the Homes of polybutadiene, and that is a really rubbery polymer (Tg = -a hundred °C) acquiring large hysteresis and therefore offering good moist grip Attributes, While using the properties of polystyrene, which can be a glassy polymer (Tg = 100 °C)
