Neoprene/SBR Open Cell Sponge


SRP has decades of converting experience with open cell sponge materials. Open cell sponge rubber is different from solid rubber in many different ways. During the process of creating rubber, manufacturers will introduce a foaming agent to virtually give the material an air-filled structure to give it that soft, sponge-like property. Open cell sponge materials are great for converting into custom gaskets.

Now, the primary difference between an open cell and closed cell sponge is the durability and compression rate. This particular type of rubber foam is a blend of SBR rubber and neoprene rubber. As a result, Neoprene/SBR Open Cell Sponge features the unique characteristics of both elastomers into one single sponge rubber form that can operate in temperatures between -40° F and 160° F. Open cell sponge rubber can be supplied with a pressure sensitive adhesive.

Fast Rebounding

The unique feature about Neoprene/SBR Open Cell Sponge is that it can rebound back to its original shape very quickly. This is because the material itself is soft. If you have an application that requires a material to be repeatedly compressed and want that material to retain its original shape, then it is highly recommended that an open cell sponge rubber be used.

Good Durability

A unique differentiator about this rubber foam is the SBR rubber used within its blended makeup. SBR is known to be a tough and physically durable elastomer. It is often employed in applications where rough, physically abrasive conditions are expected. This characteristic is transferred over to these open cell rubber sponge sheets. They can handle light to moderate physical abrasions.

Good Oil Resistance

This open cell rubber benefits from the presence of neoprene rubber in its composition. Neoprene is widely used for applications that involve the presence of oils and greases. As a result of its presence, this rubber foam material can be used for contact with light amounts of oil and grease. Oil can seriously damage and degrade most other materials, but thanks to the presence of neoprene in these rubber sponge sheets, they will last against oil for a much longer period of time.
