My watch list  


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.

  • Glas transition temperature approx. -55 °C [1]
  • 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
