Rubber Sponge

Our range of sponge rubber is available in both closed cell and open cell structures is extensive

We offer a range of densities from soft to hard according to need and can cut to the precise size and shape you need.  We are also able to offer extrusions manufactured to your requirements from this versatile material.

Southbourne Rubber (SBR) supports a wide variety of industries with sponge rubber products.  We offer both closed cell and open cell materials options according to the application and specific characteristics you are looking to utilise.  We have a full range of profiles available.

Customers across the UK and globally rely upon our sponge rubber products

What is Rubber Sponge?

Density options for this material vary from hard to soft with excellent resistance to UV, ozone and extremes of cool and warm temperatures. 

Sponge constructed from rubber is available in either an open or closed cell structure.  Closed cell rubber sponge means the air, water or chemicals cannot be absorbed into or travel through the tiny pockets.  Our closed cell silicone sponge or extrusions are fantastic as an insulator or a flexible sealant.

Our range of open cell sponge rubber is used for its ability to absorb water, air, particles such as dust or chemicals.  We offer open cell neoprene, nitrile/PVC, PU (polyurethane/polyether/polyester) and PE (polyethylene) sponge.  This is available in various thicknesses of different coil lengths and with or without self-adhesive backing.



SBR supply a range of industries with sponge rubber products.  Our primary customers come from the marine industry (both commercial and military) and aviation/ aerospace.

In the case of marine applications, we supply extrusions that are required to seal or cushion gaps between layers.  These layers are sometimes uneven in nature but this material has the ability to adapt to the surfaces it connects.  This can give a tight seal against the passage of water or air. 

Marine conditions also utilise the ability of this material to resist the absorption of water and air preventing the travel of media between the cells.  This provides excellent performance for products such as buoyancy aids and floatation devices such as fenders.
