Buna-N Sheet - 60A - Smooth Finish - No Backing - 3/8" Thick x 12" Width x 12" Length - White

Rubber-Cal’s Buna-N sheet rubber an industrial-strength synthetic rubber material that has excellent oil resistance. Substances such as oil, grease, and gasoline can easily degrade most natural and synthetic rubbers, but Buna-N (nitrile) is designed to withstand. Also known as nitrile butadiene rubber (NBR), Buna-N rubber was created to perform well in industrial, commercial, and automotive applications. Most synthetic elastomers were developed in the early 20th century to meet the newly industrialized demands of war, and nitrile rubber is no exception. Rubber NBR met an important need for the military by offering a rubber material with resistance to both natural and synthetic oils and greases. Unlike other types of synthetic rubber, nitrile rubber contains a high amount of the polymer acrylonitrile, which gives the material a long lifespan even when it is expose to oils, fuels, and grease. It is this polymer and its added benefits that set rubber NBR apart from other elastomers, and have made it a dependable industrial choice for more than 80 years.
This NBR sheet is extremely durable with a high tensile strength and good abrasion resistance. Rubber-Cal’s NBR material is actually synthetic rubber compound made up of nitrile, neoprene, and SBR to inherit the strengths of each rubber material. This gives the NBR sheet good levels of all-around resistance to oils, chemicals, and abrasions. This oil-resistant synthetic rubber has a durometer 60A, giving the rubber material a sturdy surface with moderate flexibility. The firm yet pliable nature makes this NBR sheet great for a range of high-stress applications. With a working temperature range from -20 to 180° F, rubber nitrile has increased resistance to temperature aging and can easily withstand the repeated heat and friction of industrial machinery. This versatile nitrile product is designed to handle extreme exposure in long-term applications.
The primary advantage of nitrile elastomer over other sheet rubber materials is its unrivalled oil resistance. The high amount of the polymer acrylonitrile in the rubber material gives it superior resistance to natural and synthetic oils, greases, and chemicals that can easily degrade other synthetic rubber types. It stands up to ammonia, zinc sulfate, alcohol, and mercury, among countless other substances that the nitrile rubber might be exposed to in industrial applications. This 3/8” sheet rubber is thick, but Rubber-Cal’s NBR sheet is also available in a selection of gauges, lengths, and widths to fit a range of possible applications. This grease-resistant rubber also has a crisp white hue to provide a clean aesthetic and prevent residue on sub-surfaces. The white nitrile is a non-marking material, meaning it will not leave behind unsightly stains or markings. Nitrile rubber is the perfect choice for applications in automotive and food processing settings because the elastomer sheet won’t easily degrade from chemical exposure. This unique resistance makes nitrile butadiene rubber a dependable choice for long-lasting machinery components. Whether you want to use it for protective padding or to make industrial gaskets, Rubber-Cal’s Nitrile Rubber sheets are ready for the job.
