Nitrile rubber,also known as Buna-N, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Nitrile is a form of synthetic rubber that is generally resistant to oil, fuel, and other chemicals (the more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material). It is used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, grommets, and self-sealing fuel tanks, since ordinary rubbers cannot be used. Nitrile’s ability to withstand a range of temperatures from −40 to 108 °C (−40 to 226 °F) makes it an ideal material for aeronautical applications. Nitrile is also used to create moulded goods, footwear, adhesives, sealants, sponges, expanded foams, and floor mats. Its resilience makes Nitrile a useful material for disposable lab, cleaning, and examination gloves. Nitrile rubber is more resistant than natural rubber to oils and acids, and has superior strength, but has inferior flexibility. Nitrile is therefore more puncture-resistant than natural rubbers, especially if.
