Nitrile Butadiene Rubber (NBR) is the industry standard for oil and fuel resistance. With acrylonitrile content ranging from 18–50%, NBR compounds are engineered for specific fluid resistance levels. Excellent resistance to petroleum oils, hydraulic fluids, and fuels, with good mechanical properties and abrasion resistance. Widely used for seals, O-rings, gaskets, and hoses in oil & gas, automotive, and industrial applications.
