Carboxylated Nitrile Polymer
Carboxylated Nitrile (XNBR) compounds are similar to NBR compounds with the addition of a carboxyl group included during polymerization. Carboxylation produces a stronger, more abrasion resistant material than standard nitriles.

XNBR compounds generally have higher low temperature ranges than NBR compounds and are less flexible.

PAI offers XNBR compounds in a range from 60 to 90 durometer. Black is the standard color, but we also offer tan and white compounds. Internally lubricated compounds are available for dry air applications.
