NBR Rubber Sheets
Industrial Nitrile Butadiene Rubber (NBR) sheeting engineered for supreme resistance to mineral oils, greases, diesel fuel, gasoline, and hydraulic fluids. Delivers low volume swell, high tensile strength, and minimal compression set under clamping bolts.
Types & Configurations of NBR Rubber Sheets
Standard 65 Shore A NBR Sheets
All-purpose oil resistant sheet for automotive oil pan and engine gaskets.
High-Acrylonitrile (High-ACN) Sheets
Maximum resistance to aggressive aromatic fuels, gasoline, and solvents.
Cotton / Nylon Fabric Reinforced NBR
Inserted woven fabric preventing bolt hole creep and extrusion under flange torque.
Transformer Oil Grade NBR Sheets
Specially vulcanized low-compression-set NBR for electrical transformer flanges.
Food-Grade White NBR Sheeting
FDA compliant non-toxic white nitrile sheets for edible vegetable oil processing.
