Carboxylated Nitrile(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.

 WORKING TEMPERATURE
For XNBR the service temperature is from -20℃ to 100℃ or up to 125℃. Generally higher than 100℃, life time will be shortened.
HARDNESS
50 to 90 Shore A are available
COLOR
Now Black, white and gray are available, or any color we can design for you.
APPLICATION
has been used thousands of diverse environments, including automotive, wire and cable industries.
