  • Actual shelf life could vary dramatically based on storage conditions
  • Store in a cool, dry place with temperature below 75°F
  • Keep away from direct heat or open flames
  • Avoid contact with solvents or other fluids
  • Do not store in direct sunlight
  • Keep products wrapped or sealed to minimize the absorption of moisture
  • Store in a relaxed condition free from tension, compression or other deformation

See Rubber Storage Conditions for more information about how to properly store your rubber products

SBR Products

SBR is a copolymer of styrene and butadiene and has properties similar to Natural Rubber. It has good abrasion resistance, excellent impact strength, very good resilience and a high tensile strength. The temperature range of SBR is -40˚F to +180˚F. SBR can be compounded for use as lining rubber, conveyor belt covers and other extremely demanding applications.

Our SBR Products are available in Premium, Commercial & Spec Grades or as a specialty product.
