Cabboxylated Nitrile is similar to Nitrile rubber, but the polymer backbone has been chemically modified with Carboxylic Acid containing group.
This result is XNBR with more excellent abrasion and tear resistance than traditional NBR.
For this reason, XNBR based parts are usually applied in dynamic assembly such as seals and rod wipers.
For XNBR the service temperature is from -20℃ to 100℃ or up to 125℃. Generally higher than 100℃, life time will be shortened.
