Feature
Advantage:
- Exhibiting most of the better qualities of nitrile and neoprene.
- Good resistance to oil and solvent.
- Has low swell in gasoline.
- Low temperature performance is better than either nitrile or neoprene.
- Offers much less torsional stiffness at sub zero temperatures.
- High temperature endurance is good up to 250°F.
- Good ozone weathering and water resistance.
- The abrasion is equivalent to the nitriles.
Disadvantage:
- Not recommended for ketones, esters, aldehydes, chlorinated and nitro hydrocarbons.
