SBR is a copolymer of styrene and butadiene.<\/p>\n

SBR is often blended with other rubbers such as natural rubber (NR)<\/a>, isoprene rubber (IR)<\/a>, and butadiene rubber (BR). The rubber has a chemical resistance very similar to that of natural rubber (NR). However, the tensile strength is significantly lower, though it can be improved with reinforcing fillers such as fine-grained carbon black. The elasticity and low-temperature properties are inferior to natural rubber (NR), while the heat resistance is superior. <\/p>\n

Styrene-butadiene rubber (SBR) has poor ozone resistance, which can be improved by adding EPDM<\/a> or by incorporating antiozonants in combination with protective waxes.<\/p>\n

It is used as a replacement for natural rubber (NR) in most applications.<\/p>\n

SBR is often referred to as wear-resistant rubber due to its high durability. It also reduces noise in its application. <\/p>\n
