Product Overview:For applications requiring O-rings with a broad temperature tolerance and superior resistance to compression set, hydrogenated nitrile butadiene rubber (HNBR) O-rings offer an excellent solution. These O-rings are created by hydrogenating nitrile butadiene, a process that saturates the polymer's double bonds, resulting in enhanced durability and abrasion resistance. This also boosts their resilience against ozone, heat, mechanical stress, and various chemicals, making HNBR O-rings a top choice for engineers in need of robust sealing solutions.
Material Information:When selecting HNBR O-rings, it's crucial to consider the material's acrylonitrile content (ACN), which varies from 17% to 49%. The material's performance at low temperatures decreases with increasing ACN content, while higher ACN levels provide better resistance to polar lubricants and fuels. We offer HNBR O-rings in standard hardness levels of 70, 80, and 90 Shore A, ensuring a wide range of options to cater to specific application requirements.
Advantages of HNBR O-Rings:HNBR O-rings outperform standard nitrile rubber (NBR) O-rings, offering improved toughness and temperature resistance due to the hydrogenation process. This process, indicated by the "H" in HNBR, significantly enhances the rubber's resilience even in harsh environments. With a temperature range of -23°F to 300°F, HNBR O-rings exhibit superior wear, tear, and compression resistance compared to NBR O-rings, and they also provide excellent weathering resistance.
Common Applications:HNBR O-rings are widely used in automotive, HVAC, and oil and gas industries. They are particularly effective in modern cooling systems that use R134a refrigerant. Unlike traditional neoprene O-rings, which degrade quickly in these systems, HNBR O-rings maintain their integrity, making them the preferred choice for HFC refrigerant systems. It's important to note that the compatibility of the lubricant used in these systems is crucial; R134a is not compatible with older PAG lubricants but works well with mineral oil and HNBR O-rings.
Industry-Specific Applications:HNBR O-rings are suitable for use with petroleum, fuel oils, aliphatic hydrocarbons, alcohols, diester base lubricants, silicone oils, greases, H2S, R134a refrigerants, animal and vegetable fats, ethylene glycol, salt solutions, alkalis, diluted acids, steam, and hot water up to 300°F. However, they are not recommended for use with strong acids, ethers, esters, ketones, aldehydes, chlorinated hydrocarbons, UV light, ozone, brake fluids (especially those based on glycol), polar solvents, aromatic or chlorinated hydrocarbons, and aromatic fuels.
