Rubber materials with a cellular structure where we use different types of polymers depending on which properties our customers demand.

Basic properties
EPDM
+ Weather / ozone
+ -40 - + 120 ° C
+ Allround
- Fuel / oil resistance

Nitrile (NBR)
+ Fuel / oil resistance
+ Allround
- Weather / ozone

Chloroprene (CR)
+ Allround
+ Weather / ozone
+ Fire Resistant
- Halogenic gases
- Expensive

Silicone
+ -80 - + 200 ° C
+ Compression set
+ Weather / ozone
- Tear strength
- Very expensive

The closed cell materials are in the following polymers EPDM, Chloroprene (CR), Nitrile (NBR) and Silicone.

The semi-closed cell becomes dense at a compression of min 65% found only in EPDM. These materials are usually called Nitto.
