(NBR) is a synthetic rubber commonly used in the manufacture of seals, including O-ring seals
. NBR seals have good resistance to oils, fuels, and hydraulic fluids, making them suitable for many automotive and industrial applications.
1. Good resistance to oil, fuel, and hydraulic oil.
2. Good mechanical properties, including high tensile strength and good wear resistance.
3. Limited temperature range (-40°C to +120°C or -40°F to +250°F).
4. Good resistance to compression set.
5. Moderate chemical resistance.
1. Automotive: NBR seals are commonly used in automotive applications, including engines, transmissions, fuel systems, and air conditioning systems. They are also used in braking systems to prevent leaks and contamination.
2. Industrial: NBR seals are used in a wide range of industrial applications, including hydraulic systems, pneumatic systems, pumps, and compressors.
3. Agriculture: NBR seals are used in agricultural equipment such as tractors, combines, and harvesters.
4. Aerospace: NBR seals are used in aerospace applications to seal fuel systems, hydraulic systems, and pneumatic systems.
5. Marine: NBR seals are used in marine applications, including ships, to prevent leakage and contamination of pumps, valves, and other equipment.
Overall, NBR seals are widely used in many applications due to their good resistance to oil and other fluids, good mechanical properties, and cost-effectiveness. However, it is important to select the proper material for a specific application to ensure optimum performance and reliability.
