Basic Material
Commercial Description
A 90 durometer, NBR elastomer. The properties of the nitrile rubber depend mainly on the ACN content which ranges between 18 % and 50 %. In general it has good mechanical properties with an operating temperature range of between -30 °C and +100 °C (for a short period of time up to +120 °C). NBR is mostly used with mineral based oils and greases and is a good choice for standard applications.
