Metal Closure Strips

HFP1- EPDM Real Rubber Closure EPDM/SBR blend rubber closure. This closure has an extremely fine closed cell structure. The material is highly resistant to most chemicals and is extremely stable in all weather conditions. Water absorption rates are much lower than most other closures. This product will remain flexible and is excellent for all closure applications. Gray and custom colors available.
