Styrene-Butadiene Rubber (SBR) / 丁苯橡膠

The most widely synthetic rubber in the entire world is SBR, a copolymer of styrene and butadiene. For the most part SBR rubber is used in tire by blending with natural rubber and butadiene rubber. SBR is weak and unusable without reinforcement by carbon black, but with carbon black it is strong and abrasion–resistant. The defects of SBR are poor resistant to oil and not suitable in weathering, UV, oxygen & ozone because the double bond in the polymer backbone.

Service Temperature
The Service Temperature of SBR can be designed from -55 C to 100 C.

50 to 70 Shore A are available
