Product Description

Our EPDM sponge rubber is a high-quality, closed cell material that is commonly used to create an air and watertight seal. EPDM sponge is great for use in outdoor sealing applications due to the superior UV and Ozone resistance the material offers. Aside from offering excellent weathering resistance, EPDM also features good flexibility, tensile strength and recovery properties. The closed cell structure enables the material to handle high-pressure sealing applications at a better rate. This serves to increase the life expectancy of the material in physically demanding applications.

We can supply our EPDM sponge rubber material in a wide variety of grades, densities and thicknesses as standard. This ensures that you can always get the perfect material to suit your unique requirements. We can also produce the material in a range formats such as; full rolls, sheets, strip cut lengths and bespoke gaskets.

A key feature of our closed cell EPDM sponge rubber is the materials air and watertight structure. This provides excellent thermal sealing as well as preventing the build-up of bacteria and mould. The closed cell structure also enables our material to create a seal using minimal rates of compression. However, the sealing properties of the material can vary depending on the density. Don’t hesitate to get in contact with us if you are unsure which density best suits your application.

Material Conversion Possibilities

Here at The Rubber Company we can utilise a variety of sponge rubber conversion tools and techniques. This enables us to cut, shape, drill, join and laminate our materials to match your exact requirements. Rubber sponge materials are manufactured in large blocks, so it is necessary to convert these blocks into usable end products. Our dedicated team can work directly with you every step of the way. This ensures that we use the best methods in order to achieve your desired shape and finish.
