Styrene-butadiene rubber (SBR), a general-purpose synthetic rubber, produced from a copolymer of styrene and butadiene.
SBR often mixes together with other material like NR (natural rubber), IR (Isoprene rubber), and BR (butadiene rubber). SBR is usualy used as an abrasion-resistant replacement for natural rubber.
Styrene-butadiene rubber (SBR) has a chemical resistance which is very similar to that of natural rubber (NR). Tensile strength is much lower, but can be improved by fillers such as fine-grained carbon black. The elasticity and low temperature is lower than that of natural rubber (NR), while the heat resistance is better.
Synthetic Rubber (SBR) have poor ozone resistance but that can be improved with the addition of EPDM or by adding antiozonants in combination with waxes.
