  • 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

Silicone Rubber Products

Silicone rubber can withstand a wider range of temperature extremes than nearly all other elastomers, remaining viable from -80°F to +450°F. Silicone has excellent temperature range and good compression set. Silicone can withstand many extreme environments and is inherently a fungus resistant material. It can resist water and many chemicals, including some acids, oxidizing chemicals and ammonia.
