Commercial Description:

FKM is an elastomer material known especially for its non-flammability, low gas permeability and excellent resistance to ozone, weathering, and aging. The operating temperatures of the fluorocarbon rubber range between -20 °C and +200 °C (for a short period of time up to +230 °C). FKM is also often used with mineral based oils and greases at high temperatures.
