  • 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

EDPM Rubber Products

EPDM Rubber (ethylene propylene diene monomer) provides superior properties for outdoor and high temperature applications. EPDM has excellent resistance to heat, ozone and sunlight and good resistance to alkalis, acids and oxygenated solvents. Very good temperature flexibility, superior resistance to water and steam. It is highly extendible and is sulfur and peroxide curable.

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