NBR Compounds
Valley
Rubber Mixing produces an “off-the-shelf” group of NBR compounds suitable for molding and extrusion applications. These compounds are suitable for use in belts, o’rings, seals, gaskets, industrial roll covers, diaphragms, and general purpose mechanical goods that require those characteristics typically associated with
NBR. These compounds will exhibit very good
abrasion resistance, water resistance, oil and chemical resistance, heat resistance (121°C), and gas permeability resistance.
