Product Introduction
This unique modification endows HNBR with exceptional comprehensive properties:
Outstanding Oil & Fuel Resistance: Excels in resisting degradation from mineral oils, synthetic lubricants, diesel, gasoline, and biofuels (e.g., ethanol blends), far superior to standard NBR.
Excellent Heat Resistance: Maintains physical integrity and sealing performance at continuous temperatures up to 150°C (302°F), with short-term resistance up to 180°C (356°F).
Good Abrasion & Tear Resistance: High tensile strength and elongation at break, ensuring durability in dynamic sealing applications with friction and mechanical stress.
Superior Ozone & Weather Resistance: Resists oxidation, ozone cracking, and UV radiation, suitable for outdoor or harsh atmospheric environments.
Low Compression Set: Minimal permanent deformation after long-term compression, ensuring consistent sealing performance over extended service life.
Chemical Compatibility: Resists dilute acids, alkalis, and most organic solvents (excluding strong polar solvents such as ketones and esters).
