Butadiene Acrylonitrile Rubber (NBR)

Butadiene Acrylonitrile Rubber (NBR) in Singapore

Butadiene Acrylonitrile Rubber (NBR), commonly known as Nitrile, stands out as a versatile synthetic rubber with remarkable oil-resistant properties. This synthetic rubber is created through the copolymerization of acrylonitrile and butadiene, resulting in a material that finds extensive use in various industrial applications.


1. Excellent Oil Resistance

NBR boasts exceptional resistance to oils and fuels, making it a preferred choice in applications where exposure to these substances is frequent. This characteristic extends the lifespan and reliability of products such as fuel hoses, gaskets, and rollers.

2. Good Heat Aging Characteristics

With good heat aging characteristics, NBR maintains its structural integrity and performance even under elevated temperatures. This property enhances the material’s suitability for applications where heat resistance is crucial.

3. High Gas Permeability Resistance

NBR exhibits high resistance to gas permeability, making it a reliable material in environments where preventing gas penetration is essential. This feature contributes to the material’s effectiveness in various sealing applications.

4. Excellent Chemical Resistance

The chemical resistance of NBR is another notable attribute, rendering it resilient against a range of chemicals. This property expands its utility in diverse industrial settings where exposure to different chemicals is common.

5. Low Insulation Resistance

While NBR is low in insulation resistance, its other outstanding properties often outweigh this limitation. As a result, it remains a preferred choice in applications where insulation is not the primary consideration.


The unique combination of properties makes NBR a material of choice in various applications, including:

  • Fuel Hoses: NBR’s excellent oil resistance makes it a go-to material for manufacturing durable and reliable fuel hoses.

  • Gaskets: The resilience and chemical resistance of NBR make it ideal for producing gaskets that provide effective sealing in different environments.

  • Rollers: In industrial settings, NBR is commonly used in the production of rollers, ensuring longevity and performance under challenging conditions.

  • Other Oil-Resistant Products: From seals to industrial gloves, NBR finds application in a wide array of products where resistance to oils and chemicals is critical.

Butadiene Acrylonitrile Rubber (NBR) stands as a testament to the advancements in synthetic rubber technology. Its unique blend of oil resistance, heat aging characteristics, and chemical resilience makes it an indispensable material in industries where reliability and durability are paramount. Whether in fuel systems, sealing applications, or industrial machinery, NBR continues to play a vital role in enhancing the performance and longevity of diverse products
