Commercial Description:
A 70 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. NBR is mostly used with mineral based oils and greases and is a good choice for standard applications. Used also as an energizer in T46N, M12N, Z20N, and Z52N.
