SBR Gaskets

Due to the fact that A.J. Rubber & Sponge Ltd. commonly fabricates gaskets and seals using SBR (styrene butadiene rubber), we have learned quite a bit about this material. Other common names for SBR (styrene butadiene rubber) are buna-s, buna s and GRS. SBR (styrene butadiene rubber) possesses many unique characteristics:

• The typical elongation percentage of SBR (styrene butadiene rubber) is approximately 500%.
• SBR (styrene butadiene rubber) has a recommended operating temperature range of -40°C to 100°C
  (-40°F to +212 °F).
• SBR (styrene butadiene rubber) usually transitions into a glass-like substance at a temperature of approximately -55°C (131°F), also referred to as the “glass transition temperature”.

SBR (styrene butadiene rubber) gaskets are very commonly incorporated into the production of pneumatic tires, tubes, footwear heels and soles, as well as for many custom gasket manufacturing applications. Although custom SBR (styrene butadiene rubber) gaskets and seals are quite versatile products, they tend not to be resistant to sunlight, ozone, sleet, snow, rain and/or other weather elements, and A.J. Rubber & Sponge Ltd. does not recommend using them for any type of electrical application.
