Hydrogenated Nitrile Rubber

ASTM Designation: HNBR

Standard Colour:Black

Description: HNBR is the modification of NBR rubber, where unsaturation has been removed in the main chain, to improve heat resistance, oil resistance along with other improvements.

Standard operating temperature Range: -50 OC to +160 OC

Hardness Range: 50 – 90 Shore A

Chemical Structure:

Features:

• Excellent resistance to hot oil and hot air
• Excellent resistance to oxidative and ozone degradation
• Excellent resistance to many oils, industrial chemicals, better than NBR.
• Very good mechanical properties-tensile strength, abrasion resistance etc.

Applications:

• Most of the applications of NBR, where working environment is more extreme.
