Acrylonitrile-butadiene Rubber or Nitrile Rubber (NBR) is popularly considered as a workhorse for both industrial and automotive rubber products. NBR is primarily composed of unsaturated copolymers of butadiene and acrylonitrile. Acrylonitrile-butadiene Rubber (Nitrile) NBR is a material that offers excellent resistance to oils and fair amount of resistance to fuels. A very significant disadvantages is the fact that it is not a suitable material for usages requiring prolonged exposure to UV. Typical temperature range varies from -20°C to +100°C.

For making extruded products NBR requires formulating with other ingredients and subsequent processing. The ingredients that are added include plasticizers, reinforcement fillers, vulcanization packages. Processing operation includes:

• Mixing
• Pre-forming to required shape
• Application to substrates
• Extrusion
• Vulcanization

Applications of Acrylonitrile-butadiene Rubber or Nitrile Rubber (NBR)
There are mainly two applications for extruded profiles made from Acrylonitrile-butadiene Rubber or Nitrile Rubber (NBR). They are in the following two segments.

• Automotive Applications
  In applications of automotive segment NBR is preferred in seals, fuel and oil handling hose, grommets, and other water handling applications. The advantage lies in the fact that NBR can sustain severe automotive applications, with a temperature handling range of –400C to +1250C.
  
  
• Industrial Application
  NBR finds application in roll covers, hydraulic hoses, seals for various kinds of plumbing or appliance applications.
