Nitrile (NBR) Sheet
What is NBR Rubber?
NBR rubber, also called buna-n, nitrile rubber and nitrile butadiene rubber, is a synthetic rubber manufactured from a copolymer of acrylonitrile and butadiene. NBR rubber is highly oil-resistant and is often used in the production of gaskets, rollers, fuel hoses and other rubber products in which high oil resistance is essential.

Why is Nitrile Rubber Oil Resistant?
Nitrile rubber strips are often oil resistant due to the high level of nitrile present within the polymer. This in turn results in NBR rubber having a higher resistance to oils and acids and a higher level of strength but an inferior level of flexibility in comparison to other rubber materials, such as natural rubber. Nitrile rubber’s highly resilient nature makes it the material of choice for disposable labs, examination gloves and cleaning.
Nitrile Rubber Sheet Properties
One of the most beneficial of buna rubber’s properties is its resistance to hydrocarbon oils and fuels, as well as solvents and greases. This makes nitrile rubber a popular choice for use in industrial applications whereby the product may come into contact with such media. In addition to this, NBR rubber also offers reasonable mechanical properties. Nitrile rubber sheet is available in thin gauge thicknesses from 0.5mm up to 12mm thick and is generally available in widths of 1.4m, with thin gauge options sold in 1.2m widths.
Buna-N Temperature Range
Commercial nitrile rubber sheeting has a nominal hardness of 70° and is suitable for use in temperatures of between -15°C and +90°C. NBR sheet is available to purchase to a British Standard, BS2751: 2001. This is a higher grade of nitrile rubber material, providing more superior properties than a commercial NBR rubber material and is manufactured to meet a specification, as set out by the BSI. In the BS2751 range, Nitrile rubber sheeting is available in hardnesses of 40° (known as BA40), 50° (BA50), 60° (BA60), 70° (BA70) and 80° (BA80). NBR sheet material will also be suitable for use in temperatures of between -30°C and +110°C.
