What kind of scenarios do different levels of NBR apply to?
NBR rubber can be roughly divided into three grades according to the different content, and different contents of NBR have different application scenarios.
| Low nitrile content (20-30% ACN) | Need for softness: NBR with low nitrile content usually has higher softness, suitable for parts that need elasticity. For example, the valve stem seal, the valve stem seal, which is responsible for sealing the valve stem inside the cylinder head, is usually made of nitrile rubber with a lower nitrile content because of its flexibility and low temperature performance. |
| Low temperature environments: The flexibility and low temperature performance of low nitrile NBR make it suitable for applications in cold climates, refrigeration systems and cryogenic equipment | |
| Moderate nitrile content (30-40% ACN) | General Purpose Sealing: Nitrile rubber with a medium nitrile content is typically used in general purpose sealing applications, including automotive oil pan gaskets, which require a medium nitrile content to achieve a balance of oil resistance and flexibility. |
| Hydraulic systems: It is used for hydraulic seals and components that require moderate oil resistance and hydraulic oil. | |
| High nitrile content (ACN more than 40%) | Oil and gas industry: Nitrile rubber with high nitrile content is widely used in the oil and gas industry for seals, gaskets and components in drilling equipment, pipes, valves and pumps, with excellent resistance to hydrocarbons, drilling fluids and aggressive chemicals. |
| Chemical Processing: High nitrile NBR is suitable for applications exposed to many chemicals, acids and solvents. It is used for seals, gaskets and diaphragms in pumps, valves and reactors in chemical processing plants | |
| Automotive engine seals: NBR with high nitrile content is used in engine seals, gaskets and other parts requiring excellent resistance to oil, fuel and high temperature environments, such as cylinder head gaskets and rear main seals | |
| Aerospace and Defense: It is used in seals, gaskets, o-rings and components in aerospace and defense applications where resistance to aviation fuels, lubricating oils, hydraulic fluids and high temperatures is critical. |
In short, nitrile Butadiene Rubber (NBR) continues to revolutionize the way we manufacture and develop products across industries. Its excellent resistance to chemicals, oil, and extreme temperatures, combined with its durability and flexibility, make it a valuable material in countless applications. From automotive seals and gaskets to medical gloves and industrial hoses, NBR’s versatility and reliability make it the first choice for engineers and manufacturers worldwide. With the advancement of technology, nitrile rubber derivatives also continue to appear. For example, HNBR obtained by special hydrogenation of nitrile butadiene rubber further improves the performance of NBR. The continuous development of the field of nitrile rubber undoubtedly indicates unlimited possibilities. Embrace NBR and explore the mysterious realm of treasure.
