307 – Styrene Butadiene Rubber (SBR)

ASTM D-2000 classification: AA, BA


Temperature Range:

-25° to + 75°C.



SBR is a synthetic elastomer suitable for low to medium duty applications involving air, water and diluted mixtures for, economic and general purpose applications.

It has excellent physical properties including abrasion resistance, good tensile strength, low compression set and high tear properties and is also resistant to many organic salts and acids, and some organic solvents.
