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.

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