Nitrile Butadiene Rubber (NBR) is a synthetic elastomer made from butadiene and acrylonitrile, designed specifically for applications requiring resistance to oils, fuels, and chemicals. Its defining feature is its excellent performance in contact with petroleum-based substances, which makes it a preferred choice for automotive, aerospace, and industrial applications. NBR can withstand continuous exposure to temperatures from -40°C to 120°C, maintaining flexibility and durability under demanding conditions. Its tensile strength, abrasion resistance, and sealing ability make it ideal for gaskets, O-rings, seals, hoses, and fuel system components. Additionally, nitrile gloves are widely used in the healthcare and industrial sectors as a safer alternative to latex. Variants like Hydrogenated NBR (HNBR) enhance performance by providing greater resistance to ozone, heat, and aging. While it offers excellent durability in oil-rich environments, NBR has moderate weather and ozone resistance, requiring stabilizers for outdoor use. Environmentally, NBR is non-biodegradable and has limited recycling pathways, but its critical role in safety and reliability makes it irreplaceable in many industries. With its superior oil and chemical resistance, NBR remains a cornerstone material for sectors handling fuels, lubricants, and solvents.
