NBR is the standard material for hydraulics and pneumatics. NBR resists oil- based hydraulic fluids, fats, animal and vegetable oils, flame retardant liquids ( HFA, HFB, HFC), grease, water, and air. Special low-temperature compounds are available for mineral oil-based fluids. By hydrogenation, carboxylic acid addition,. This Nitrile durometer (70A) specifications chart will help you determine if these Nitrile material properties will be compatible with your rubber or O-ring seal application.

We can change the formulation of the rubber so that the specifications meet your needs.
