XNBR
Characteristics
Cabboxylated Nitrile is similar to Nitrile rubber, but the polymer backbone has been chemically modified with Carboxylic Acid containing group. This result is XNBR has more excellent abrasion and tear resistance than traditional NBR.

Service Temperature
For XNBR the Service Temperature is from -20℃ to 100℃ or up to 125℃. Generally when the temperature is higher than 100℃, service life will be shortened.

Hardness
50 to 90 (Shore A).

Color
Black, white and gray are available, or any assigned color from customers.

Application
XNBR based parts are usually applied in dynamic assembly such as seals and rod wipers.
