XNBR (Carboxylated Nitrile)
Selection Guide
XNBR O-rings, gaskets, & custom molded parts are similar to Nitrile, but the backbone has been chemically modified with a Carboxylic Acid group. The resulting elastomer is a Nitrile rubber with outstanding abrasion and chemical resistance, superior to that of traditional Nitrile. This makes XNBR O-rings, gaskets, & custom molded parts well suited for a wide variety of applications, including many dynamic applications. The added strength and abrasion resistance of XNBR make these seals, O-rings, gaskets, & custom molded parts popular for reciprocating parts in heavy industrial applications.
Carboxylated Nitrile O-rings, gaskets, & custom molded parts are great for many static applications as well, check with one of Canyon’s helpful product engineers for an expert seal recommendation.
Common names include: XNBR (Carboxylated Nitrile) Trade Names: Nipol®, Krynac®, Paracril®
Features of XNBR

Limitations of XNBR
-
XNBR O-rings, gaskets, & custom molded parts have poor resistance to ozone, direct sunlight, UV, and weathering
-
XNBR O-rings, gaskets, & custom molded parts have poor resistance to aromatic fuels, glycol-based brake fluids, polar solvents, non-flammable hydraulic fluids (HFD), aromatic/chlorinated hydrocarbons, ketones, esters, and aldehydes
-
XNBR O-rings, gaskets, & custom molded parts have a Service Temperature Range of (varies with application): -20°F to 302°F ( -30°C to 150°C)
