General Characteristics
Styrene-Butadiene Rubber (SBR) is a versatile synthetic rubber known for its affordability and reliable physical properties. While not as oil-resistant as some specialty rubbers, SBR performs well in a range of industrial applications where durability, abrasion resistance, and cost-efficiency are key.

SBR Rubber Properties & Performance Characteristics
SBR offers an economical solution for applications that do not require oil resistance. It provides good water resistance, flexibility, and resilience—particularly in compounds with durometer ratings up to 70A. At higher durometers, compression set resistance tends to diminish. SBR performs satisfactorily in environments involving mild chemicals, wet or dry organic acids, and general-purpose industrial conditions.
However, SBR is not suitable for exposure to ozone, strong acids, oils, greases, fats, or most hydrocarbons, as these can cause rapid degradation.
Benefits of SBR
Common Uses for SBR Rubber
SBR (Styrene-Butadiene Rubber) is widely used in applications where affordability and general-purpose functionality are important. Its resilience and durability make it a popular choice for conveyor belts, flooring mats, and automotive components such as bumpers and gaskets. It’s also commonly used in non-oil-resistant seals, washers, and general-purpose gaskets. Additional applications include shock-absorbing pads, strips, and blended formulations for footwear soles and tires. SBR performs well in indoor or controlled environments where oil resistance isn’t required but water resistance and abrasion durability are essential.
