SBR Red Rubber

Styrene Butadiene Rubber (SBR) is synthetic, low-cost red rubber material comprised of styrene and butadiene monomers. It is made as a replacement for natural rubber. The red rubber gasket material is specially designed to be quick-sealing, non-hardening, and heat-resistant for use in various flanged applications. Our SBR red rubber is available in shore “A” hardness of 60 up to 80 durometer, with a temperature range of -20 to +120°F (-28 to 48°C). It has a red, smooth plate finish and is one of our most popular gasket materials.

Like many other synthetic rubbers, SBR has enhanced properties that gives better physical, wear, water heat-aging, and abrasion resistance, making it an economical choice for gasket material. SBR is durable with excellent impact strength, great resilience, and high tensile strength to suit extremely demanding applications. It is also flexible enough to conform to uneven flange surfaces.

SBR can resist most weak and moderate organic acids, hot or cold water, alcohol, ketones (acetone), non-mineral oil based brake fluid, Silicone Oil, glycol and aldehydes. However, this material has poor resistance to ozone, sunlight, strong solvents, most hydrocarbons, mineral oil and petroleum-based fluids and its fatigue resistance and low temperature properties remain inferior to natural rubber.
