STYRENE-BUTADIENE

'Styrene-Butadiene' ('SBR') is an elastomeric copolymer consisting of styrene and butadiene. It has good abrasion resistance and good aging stability. SBR is stable in: mineral oils, fats, aliphatic, aromatic and chlorinated hydrocarbons.

★ Possible temperature range: approx. -40 to +100 °C (-40 to +212 °F)

★ Chemical Type: styrene-butadiene (copolymer)

★ Trade names (common): 'GRS', 'Buna S' (SBR)

★ Elongation (%): 450-500

★ Useful temperature range: -60 to 120 degrees Celsius (-75 to 250 degrees Fahrenheit)

★ Major application characteristics: good physical properties; excellent abrasion resistance; not oil, ozone, or weather resistant; electrical properties good, but not outstanding

★ Typical applications: pneumatic tires and tubes; heels and soles; gaskets
