Product Description

Our white closed cell EPDM sponge rubber is a high-quality as well as highly versatile sealing and packaging material. The white colour makes this material ideal for applications where the sponge will be seen. We regularly supply this material for use in product presentation as well as decorative trim applications. As a closed cell material, our white EPDM sponge is both air and watertight. This enables it to create a seal using minimal pressure. It is worth noting however, that too much pressure can cause the cell walls to burst, which can reduce sealing functionality. This is a soft to the touch material that we can supply in densities from 120 to 160kg/m3.

We can supply this sponge material in a variety of thicknesses from 1mm to 40mm as standard. We can also laminate the material or join multiple sheets together in order to create greater thicknesses. Aside from rolls we can cut the material into bespoke sheets, strips and gaskets to match your specific requirements.

Our white closed cell EPDM sponge is ideal for use in both interior and exterior applications. This is due to the excellent weathering, UV and ozone resistance the material provides. EPDM sponge also features a good combination of durability and flexibility. This enables you to use our material in physically demanding applications as well as applications with complex and irregular shapes. We manufacture this material from a cellular EPDM rubber that is CFC, halogen and HCFC free.

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.
