Styrene Butadiene Rubber (SBR)
Styrene Butadiene Rubber (SBR)
Styrene-butadiene rubber (SBR) is a general-purpose synthetic rubber and sometimes used as a substitute for natural rubber. It can be produced by free-radical solution polymerization or by emulsion polymerization either warm at 30 to 60°C (hot rubber) or cold at temperatures near 0°C (cold rubber). It has good abrasion resistance and aging stability when protected by additives.
Types
- SBR 1502, SBR 1500
- SBR 1705, SBR 1712
- SBR 1723, SBR 1739, SBR 1783
- HSR
Uses of styrene-butadiene rubber (SBR)
The majority of SBR used is in light application automotive tires and parts. Because of its inferior heat resistance to natural rubber, it’s used in lessening proportions in car tires up to high performance or heavy-duty tires. Heavy duty applications like airplane tires are fully natural rubber and need more heat resistance. SBR is also used for automotive parts, including drive couplings.
Apart from its automotive applications, SBR can also be found in industrial applications as belting, insulation for wire and cabling, haul-off pads, roll coverings, hoses, gaskets, seals, and coated fabrics, thanks to its abrasion resistance. SBR is especially used for rubber gaskets, thanks to its metal adhesion and abrasion resistance. On the more commercial side, SBR is included in shoe soles, carpet backing adhesive, and in molded rubber goods.
