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.
Chemical Structure:
Standard operating temperature Range: -50 OC to +160 OC
Hardness Range: 50 – 90 Shore A
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.
