XNBR
Carboxylated Nitrile(XNBR)
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.
Cure system - Sulfur-Cured
Standard XNBR compounds are sulfur-cured.
