NBR O-Ringsexhibit excellent performance in terms of oil resistance, abrasion resistance, temperature resistance and aging resistance, and are suitable for sealing applications in a variety of industrial fields.

1. Oil resistance: NBR O-rings have good oil resistance and can be used in different media such as lubricating oil, fuel oil and hydraulic oil, etc. They are not easy to be eroded by solvents and oils, which ensures stable and reliable sealing effect.
2. Abrasion resistance: NBR O-rings have good abrasion resistance, can be used for a long time in high-speed rotation or frequent friction environment, reduce the leakage caused by wear and tear.
3. Temperature resistance: NBR O-rings show good temperature resistance at general working temperatures, and can usually work normally in the temperature range of -40℃ to +100℃. At the same time, it is also possible to improve its temperature resistance range by selecting special formulations.
4. Aging resistance: NBR O-rings have a certain degree of aging resistance, and can be used for a long time under the environment of oxygen, ozone and sunlight ultraviolet rays without significant aging, hardening or deterioration.
5. High elongation at break: NBR O-Rings have a high elongation at break and a certain degree of elasticity and ductility, making them suitable for sealing applications that require them to withstand axial or radial deformation.
6. High cost-effectiveness: NBR O-Rings are relatively inexpensive, have a mature manufacturing process, are widely used in a variety of industries, and have good durability and a long service life, making them highly cost-effective.
