Styrene Butadiene Rubber | SBR

Clwyd reference	SBR
ASTM classification	SBR
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
