Nitrile Rubber O Ring Cord Features
1. Good sealing and damping: Nitrile O-rings have good sealing properties and are the best choice for seals. They can effectively prevent the penetration of both gas and liquid.
2. Aging and ozone resistance: Working in an oxidizing and ozone environment, it can still maintain its stable physical properties.
3. Chemical stability/corrosion resistance: Nitrile rubber can resist many non-polar solvents. It also has a certain resistance to weak acids and weak bases, making it the best choice material in the chemical industry.
4. Oil resistance: Oil resistance is one of the most significant features of nitrile rubber. NBR O-rings’ excellent resistance to oil, fuel, and other fats makes them widely used in automotive applications.
5. Pressure resistance: Under long-term pressure, the nitrile O-ring can also better restore its original state, thus achieving a long-term effective sealing effect.
6. Wear resistance: Nitrile rubber has high wear resistance and tear resistance. In medium and low temperature environments, nitrile rubber can better maintain its sealing.
7. Electrical insulation: The insulation of nitrile O-rings is average. As the ambient temperature rises, the insulation will decrease. Therefore, when choosing nitrile O-rings, its working environment should be considered.
8. Flame retardancy: The flame retardancy of nitrile depends on the halogen content in the molecular structure. By adding halogen flame retardants, we can improve the flame retardancy of nitrile O-rings.
Nitrile Rubber O Ring Cord Advantages
- Nitrile rubber O-rings have a wide temperature range. They can work normally in the range of -40°C to 120°C and are suitable for low—and medium-temperature environments.
- Nitrile rubber O-rings are cost-effective. Compared with fluoro rubber, nitrile rubber is relatively low and can also meet the application needs of various scenarios.
- Nitrile rubber has excellent oil resistance. It has good resistance to petroleum, crude oil, gasoline, water, etc. This property makes nitrile O-rings widely used in the automotive, marine and aerospace industries.
- Nitrile rubber can be formed by processes such as extrusion and molding. We have more shapes and sizes of O-rings for you to choose from.
- NBR rubber has good heat aging resistance. This property is better than natural rubber, EPDM rubber, and CR rubber.
- Nitrile rubber ages as fast as natural rubber and other materials. It is also an excellent material choice for applications that require wear resistance and metal adhesion.
- Nitrile is a versatile and highly resistant material. It can be used not only in applications involving oil, fuel, and chemical resistance but also in applications requiring resistance to heat, abrasion, water, and gas permeation. From oil rigs to bowling alleys, nitrile rubber can be the right material for your application.
Applications of Nitrile O-Rings
Seashore’s Nitrile O-rings (NBR O-rings) are a common seal. Due to their excellent performance, they are widely used in various industrial fields. The following are the main application scenarios for nitrile O-rings.
Automotive industry: Due to their good oil resistance and high temperature resistance, O-Rings are often used to seal the engine, gearbox and brake system of automobiles.
Industrial machinery: Due to their reliable sealing and oil resistance, O-Rings are often used to seal compressors, valves, hydraulic systems and other parts of mechanical equipment.
Construction industry: Due to their excellent waterproofness and safety, O-Rings are often used to seal household doors and windows.
Food processing industry: O-rings are often used to seal food processing machinery or food tanks. Our products meet relevant food safety standards and have FDA certification qualifications.
Although Nitrile O-rings have many advantages, they are unsuitable for all environments. When choosing O-rings, you need to consider their working medium, temperature range, and pressure level. Contact us, and we will provide you with professional solutions.
