SBR - Styrene Butadiene Rubber

Clwyd referenceSBR
ASTM classificationSBR

SBR has good physical strength, tear and abrasion resistance. Applications include non-mechanical high-volume products such as shoe soles and heels or car tyres, gaskets, chewing gum.

Typical applications
  • Non-mechanical high-volume products such as shoe soles and heels or car tyres
  • Gaskets
  • Chewing gum
Advantages
  • Good physical strength
  • Good tear and abrasion resistance
  • Good ageing stability
  • Better wet skid resistance to NR
Disadvantages
  • Does not resist oil or fuels
  • Prone to weathering
  • Lower resilience to NR
  • Inferior heat build-up to NR
