Cellular rubber

Cellular rubber made by KÖPP is the ideal material for sealing, insulating, isolating, damping and rattle prevention. That is why this cost-effective material is used successfully throughout industry. The material can be supplied in blocks, sheets or rolls. It can be punched, milled or customised to your requirements. It is also available in a self-adhesive a self-adhesive version. KOEPPcell® cellular rubber can be processed in many different ways.

Cellular rubber - the material

Cellular rubber is a porous, closed-cell rubber quality, which is available in various resistance ratings and densities. It is manufactured using the expansion process. It is based on natural rubber or synthetic rubbers such as EPDM and other elastomers.

Cellular rubber is airtight and watertight, so it does not need any external skin to be used as a seal (unlike sponge rubber).
Our KOEPPcell® range offers you the following types of cellular rubber and elastomers, with our usual high quality at competitive prices:

Natural rubber (NR-L, NR-S)
EPDM (EPDM-L*, EPDM-S*, EPDM-SUW*, EPDM-W*)
* all also peroxide-cured
Chloroprene rubber (CR-L, CR-S)
EPDM-PE blend

Technical data

Processing methods

Perfect semi-finished products – good news for our customers

We process our own cellular rubber blocks for our processing customers in such a way that they can include them directly in their production procedures. We have a broad selection of machine tools installed, so we are in a position to supply sheets and endless rolls. We can split precisely from 1 mm thicknesses and apply various adhesive coatings on request.

Depending on the application, we can process sheets and rolls for dealers and industrial end users to make cut-outs, punched items, strips and profiles, or we can lathe or mill the material. The material can also be processed using water jet cutters.
