How to Preserve Rubber Shelf Life and Properly Store Rubber Products

The recommended rubber shelf life may vary based on polymer type and compound formulation. The actual life could vary dramatically based on storage conditions. As a fully integrated manufacturer, WARCO is equipped to formulate custom compounds specifically designed for your application. Please contact us to discuss your needs.

Technical director, Shi Hwang has also written an in-depth article that takes a detailed look at rubber’s shelf life and storage conditions.

Recommended 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 absorption of moisture
  • Store in a relaxed condition free from tension, compression or other deformation
