Nitrile Butadiene (NBR) Material Manufacturer
Seals, O-Rings & Gaskets & More
Nitrile rubber is a synthetic rubber that provides excellent resistance to petroleum-based oils as well as mineral and vegetable oil. Timco Rubber can work with your business to design and provide nitrile seals, NBR o-rings, and other parts customized for the specific needs of your applications.
Nitrile Rubber: A Material Made for Oil Resistance
Unlike natural rubber and other materials, nitrile gaskets and other parts are more resistant to heat aging. This feature is a key advantage, as it allows nitrile to not harden and lose its damping capability as quickly as natural rubber and other solutions. Nitrile rubber is also a great material choice for applications that require abrasion resistance and metal adhesion.
Due to its versatility and strong resistances, nitrile material is used in applications involving not only oil, fuel, and chemical resistance, but also those that require resistance to heat, abrasion, water, and gas permeability. From oil rigs to bowling alleys, nitrile rubber can be the right material for your application.
Timco works with a wide variety of companies to provide custom molded and die cut nitrile parts with demanding physical properties. Whether you call them Buna-N seals, NBR o-rings, or something else, our team can design and provide the best, most cost-effective custom molded or die cut parts for your applications.
What is Nitrile (NBR)?
NBR – also called nitrile-butadiene rubber, NBR rubber, and Buna-N – has been an effective rubber material option for a long time. Nitrile was first developed by BASF and Bayer in 1931, with commercial production starting four years later in 1935.
Nitrile is a synthetic rubber copolymer that is created when acrylonitrile (ACN) and butadiene are bonded together using polymerization. NBR can be made with varying levels of acrylonitrile, with higher CAN content providing added resistance to hydrocarbon oils and lower CAN content providing improved flexibility.
After the polymerization process, NBR is formed into a sheet rubber. The sheet rubber goes through vulcanization with different ingredients to improve certain performance qualities like elasticity, puncture resistance, and more. The resulting compound can then be die cut, extruded, or manufactured some other way into a variety of parts, such as seals and o-rings.
