Nitrile Rubber
Nitrile rubber, also called nitrile-butadiene rubber (NBR) or Buna-N, is a synthetic rubber that finds a great deal of use in applications that require resistance to petroleum oils and gasoline. It is a copolymer formed of acrylonitrile and butadiene molecules and can stand up to a wide range of temperatures and environments.

NBR Properties
BUNA-N properties include a range of capabilities, features, and characteristics. It can withstand temperatures ranging from -40°C up to 108°C. It is unlikely to swell due to oil exposure and is less permeable to gas when compared to other rubber materials. It is three times more resistant to punctures than natural rubber, cheaper than fluoroelastomers, and remains flexible at lower temperatures.
Buna-N Characteristics
NBR is a good fit for a variety of rubber parts due to its high-performance abilities in extreme temperatures, general toughness, and other characteristics, such as:
- Specific Gravity: 1.00
- Tensile Strength, PSI—Pure Gum: 600
- Tensile Strength, PSI—Reinforced: 3000
- Practical Shore A Hardness Range: 20-95
The Benefits of Using Nitrile Rubber Parts
Nitrile rubber brings many advantages to your custom rubber part production. It is generally resistant to many hydrocarbons, fats, oils, greases, hydraulic fluids, and chemicals. Other beneficial Buna-N properties include:
- Excellent abrasion and moisture resistance
- Excellent permeability
- Excellent resistance to oil, gasoline, and animal or vegetable oils
- Good heat, diluted acid, and solvent hydrocarbons resistance
- Good low-temperature flexibility
- Good compression set
- Fair resilience to tearing, oxidation, and concentrated acids
Buna-N’s Limitations
Nitrile rubber has uses in many industries and applications, but it is not an ideal material for every production. It is generally attacked by keytones, esters, aldehydes, chlorinated and nitro hydrocarbons, and features poor dielectric properties and flame resistance. Another rubber material will be your best option if your products are used in applications involving these elements. Download our properties of rubber chart to learn more about your choices. We also offer in-house custom rubber and elastomer compounding services for specialty products.
Industrial Uses of Nitrile Rubber Parts
Nitrile rubber is non-toxic, cost-effective, and versatile, making it a popular choice in an extensive range of rubber manufacturing productions:
- Carburetor and fuel-pump diaphragms
- Custom die-cut gaskets
- Static and dynamic hydraulic seals
- Printing/graphic arts rollers
- Rubber extrusions
- And much more!
