Nitrile Rubber Properties & Performance Characteristics
Nitrile rubber (NBR) is a general-purpose oil-resistant elastomer valued for its excellent resistance to petroleum-based oils, solvents, water, and hydraulic fluids. It also provides good abrasion resistance, tensile strength, and low compression set, making it a durable choice for demanding environments. However, nitrile is not suitable for use in highly polar solvents such as acetone or MEK, nor in applications involving ozone, chlorinated hydrocarbons, or nitro hydrocarbons.

Common Uses for Nitrile Rubber
Nitrile rubber is widely used in applications requiring oil and fuel resistance, making it a top choice for automotive, aerospace, and industrial sealing components. It’s commonly found in O-rings, gaskets, fuel hoses, hydraulic seals, and diaphragms where resistance to petroleum-based fluids is essential. Due to its durability and performance under pressure, it’s also used in off-road equipment, marine environments, and industrial machinery exposed to oils, greases, and wear-intensive conditions.
