What is nitrile rubber sheets?

Nitrile rubber sheets is also called NBR or Buna-N, Perbunan. Nitrile rubber is a synthetic rubber copolymer of butadiene and acrylonitrile – ACN. It has trade names including Nipol, Krynac, also Europrene.

Nitrile butadiene rubber has physical and chemical properties which vary depending on the polymer’s composition of nitrile. Nitrile rubber sheet is generally resistant to oil, fuel, and other chemicals. The more nitrile contents within the polymer, the higher the resistance to oils, but the lower the flexibility of the material will be.

NBR is used in the automotive and aeronautical industry to make fuel and oil handling hoses, grommets and seal. It is applied to the nuclear industry to make protective gloves. Its ability to withstand a range of temperatures from -40 to +108 °C makes it an ideal material for aeronautical uses. We also use B200000 to create molded goods, sealants, sponges, footwear, adhesives, floor mats and expanded foams.

Nitrile rubber sheet has good resilience, which becomes a useful material for examination gloves, disposable lab and cleaning. Nitrile rubber sheetings are more resistant than natural rubber sheets to oils and acids. However it has inferior strength and flexibility. NBR is generally resistant to aliphatic hydrocarbons but can be attacked by ozone, esters, ketones and aldehydes.
