What is nitrile rubber? Nitrile is a popular elastomer used for a wide range of components and applications, such as washers. It has a series of different properties that make it ideal for use in many different industrial environments. But, like many other rubber materials, its pros and cons will determine whether it’s right for you. Stephens Gaskets, is a leading supplier of nitrile rubber washer, we can help. Nitrile falls under a few different names including:

  • Nitrile Rubber
  • Buna-N
  • NBR

Nitrile Rubber | What Is It?

Nitrile (commonly referred to as NBR rubber and Buna-N) is a synthetic rubber copolymer made from acrylonitrile and butadiene. It is a collection of unsaturated copolymers, 2-propenenitrile and butadiene monomers (1,2-butadiene and 1,3-butadiene). Its composition will determine the physical and chemical properties the material has. But, a general rule of thumb is that the higher the nitrogen content is within the polymer, the stronger its resistance to oils. Therefore, lowering its flexibility. Although nitrile rubber is more resistant to roils and acids than natural rubber, a key disadvantage of the material is its inferior flexibility.

Using Nitrile | Nitrile Rubber Washer

With a range of versatile properties belonging to the material, nitrile rubber is used across a huge variety of applications. Some of which include: washers, O-rings, gaskets, oil seals, vehicle transmission belts, hoses, and cable jacketing.

Industries that use nitrile rubber vary, but nitrile components are often for use to support the aerospace, marine, and military sectors.

The Pros 

Nitrile offers the following benefits:

  • Great tear resistance
  • Rebound
  • Non-polar solvent resistant
  • Good oil resistance
  • Water resistant
  • Fantastic abrasion resistance
  • Less expensive than fluoroelastomers

The Cons 

Some disadvantages of nitrile rubber include:

  • Poor resistance to ozone, weather, and sunlight
  • Minimal resistance to high temperatures
  • Poor flame resistance

Its physical and chemical properties vary depending on the polymer’s composition of nitrile. The more nitrile there is within the polymer, the higher its resistance to oils but the lower its flexibility. Nitrile rubber is more resistant than natural rubber to oils and acids, and has superior strength, but suffers from inferior flexibility.
