HNBR Rubber - Hydrated Nitrile Butadiene Rubber

16/3/2003· HNBR is great in an environment of diluted acids, bases and salts. This also applies to situations where these environments are accompanied by increased temperature and acid gases or glycol mixtures. The elevated temperature is exactly 150 degrees Celsius. Sometimes HNBR can periodically withstand temperatures as high as 190 degrees Celsius.


The typical service temperature of FKMs is between -20°C (-5°F) and +230°C (+445°F). They can, however, withstand temperatures up to 300°C for a short period of time. However, at high service temperatures FKMs are weak, so that the design must prevent any high loads. Notes. Viton ® is a registered trade mark of DuPont Performance Elastomers.
