Chloroprene rubber, also often called chlorobutadiene rubber, polychloroprene or simply chloroprene CR, is a high-quality synthetic rubber built up from chloroprene monomers. There are many polymerisates of the monomer chloroprene significantly differing from the structures of their polymers. The variety of elastomers is increased by CR compounds with other types of rubber. Steinbach AG, for example, manufactures high-quality insulating mats from a special CR compound according to the VDE DIN standard DIN EN 61111, the mats being flame-resistant (DIN 75200).


Chloroprene rubber acts electrically insulating and is resistant to mineral oil, sulphuric acid and ozone. Moreover, the elastic material shows a generally good resistance to chemicals and ageing as well as a high flame resistance. However, it is not resistant to fuels. The mechanical properties of CR compounds, in general, are better than those of most other types of synthetic rubber.

Range of use and areas of application

Typical applications for chloroprene rubber are insulations for live operating resources. Additionally, flat seals can be made out of CR rubber. Further areas of application and use are cable sheaths, abrasion-resistant pump tubes, conveyor belts, drive belts and other technical rubber goods.

Our available dimensions for chloroprene rubber

You will receive our chloroprene CR as rolled or plate goods as well as waterjet cutting of high quality, for example for insulating cloths, insulating mats or flat seals. For the cutting we use a modern waterjet cutting machinery making complex geometries and widths possible up to 3200 mm. We deliver starting already at a quantity of 1 piece and so we offer you an expertise that you will hardly find with other suppliers. If you want to use our service, please call us, use our contact form or send us an e-mail.
