Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene. [1] Trade names include Perbunan, Nipol, Krynac and Europrene. This rubber is unusual in being resistant to oil, fuel, and other chemicals.

PREMIUM NITRILE (BUNA–N) This Premium Grade Nitrile is formulated to give maximum oil resistance and longer service life in demanding applications. Able to withstand a temperatures range of -30°F to +220°F this material comes untrimmed with a smooth blended finish. Specifications: Durometer Hardness (Shore A ± 5) Thickness

Buna-N can be customized in infinitely different ways depending on its use and any specific standards it needs to adhere to. It can also be cured with sulfur or peroxide, which affects its temperature, hardness, and compression properties.

A durometer scale is a type of measurement for rubber material hardness. The rubber durometer chart below gives you an idea of the rubber hardness that you want for your application. Generally, most rubber materials fall under the rubber durometer scale of Shore A.

70 Durometer, Black, Metal Detectable, FDA Compliant Buna-N Technical Datasheet Common Names: NBR (acrylonitrile butadiene rubber), Buna-N, Nitrile. General Description: Most commonly used general purpose o-ring material because of relative low cost, good mechanical properties, and basic resistance to many common lubricants.

Nitrile also has Shore A hardness rating from 40 to 90, an excellently low compression set value, high tensile strength ranging from between 200 and 3,500 PSI, elongation ratings of between 300 and 650%. Please view the tables below for more material information.

Mykin’s RN00170, Nitrile (BUNA-N) 70 durometer, is a general purpose copolymer of butadiene and acrylonitrile. This compound has a relatively high acrylo content, making it exceptionally resistant to petroleum base oils and hydrocarbon fuels over a temperature range of …

Hardness: Shore A 40 to 90. Tensile Strength: Varies from 14 MPa to 31 MPa depending on the grade. Elongation at Break: Typically, 200% to 600%. Tear Strength: Exhibits good tear resistance. Temperature Range: Generally stable in a temperature range of -30°C to 120°C (-22°F to 248°F). Thermal Conductivity: Low thermal conductivity.

NBR is a synthetic rubber sold as Nipol, Krynac and Europrene, known for resisting oil, fuel, chemicals and withstanding temperatures between −40 and 226 °F.

NBR (acrylonitrile butadiene rubber), Buna-N, Nitrile. Most commonly used general purpose o-ring material because of relative low cost, good mechanical properties, and basic resistance to many common lubricants. Specific physical and chemical resistances vary by compound formulation.
