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
It meets a huge variety of requirements
As a manufacturer and dealer, we can offer you an outstanding variety of different qualities and resistance levels for you to choose from on the basis of the focus of your application and your requirements. The following are the most important properties:
- Outstanding sealing
- Low thermal conductivity value (≤ W 0.1 W/mK)
- High compressibility
- Good insulating properties
- Low water absorption
- Flexible processing options
- Can be sulphur or peroxide-cured
- High resistance to temperature and ageing(EPDM)
- Highly flame-resistant and oil-resistant (CR/NBR)
- High elasticity (NR)
- Economical, as it comes straight from the manufacturer
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.
Applications for cellular rubber
One solution for many markets
Thanks to its reliable performance for sealing, insulating, isolating and padding, KÖPP cellular rubber is to be found in virtually every area of life. This includes the automotive sector, construction, mechanical engineering, and the furniture and textile industries.
