Styrene-Butadiene Rubber (SBR)

Styrene-Butadiene Rubber (SBR) Roll

Styrene Butadiene Rubber is the most used rubber and accounts for 45% of all rubber produced. SBR is a family of copolymers made by polymerising styrene and butadiene. SBR is a relatively inexpensive and general-purpose rubber which can often be used as a good substitute for natural rubber. SBR usually has superior abrasion resistance and heat aging properties compared to NR. However, SBR typically has less resilience and strength.

The double bond in the polymer chain makes SBR very susceptible to attack by ozone and oxygen.

Key Properties of SBR:

  • Lower Cost
  • Comparable properties to NR
  • High tensile strength
  • High resilience
  • Heat resistance
  • Flexible in low temperatures

Operating Temperature Range: -25 to +100 °C

Chemical Compatibility:

  • Resistant to water, organic acid, ketone, chemical, alcohol, and aldehyde.
  • Not resistant to oil or fuel.
  • Can be prone to weathering.
  • Susceptible to ozone and oxygen attack.

Typical Applications:

  • Car tyres
  • Shoe soles
  • Drive couplings
  • Haul-off pads
