Semi Open Cell EPDM

Advanced Seals & Gaskets Ltd manufacture a diverse range of Semi-Open Cell EPDM Sponge products. Semi-Open Cell EPDM is an extremely soft and flexible EPDM sponge rubber.

The cell structure of Semi-Open Cell EPDM is created in the manufacturing process by physically "bursting" the closed cell structure in order to create a product that is softer and therefore easier to compress than the more traditional sponge rubber. This also means that Semi-Open Cell EPDM offers much better recovery after compression. Advanced Seals & Gaskets Ltd are able to manufacture a wide variety of products from Semi-Open Cell EPDM Sponge including:

All of the above can be manufactured in either plain or self-adhesive backed, peel-able liner on one or both sides. The super-soft nature of Semi-Open Cell EPDM provides excellent sealing capabilities once compressed. Due to low compression load, the foam can compensate for dimensional deviations in substrates and can, therefore, be applied to both rough, smooth and low energy surfaces. Semi-Open Cell EPDM is used many different applications and industries including automotive, HVAC units, air duct sealing, etc.
