Project details

The O-ring NBR 70 is a sealing ring made of nitrile rubber (NBR) material, which has excellent oil resistance, heat resistance, and wear resistance. Its operating temperature range is -30 ℃ to+110 ℃, and it can maintain good sealing performance in most common oils and chemicals. It also has good mechanical strength, elasticity, and processing performance, making it easy to process and install. In addition, it has good resistance to some polar solvents, but is not acid resistant, cold resistant, has poor electrical insulation, and is not resistant to polar solvents.

It should be noted that the O-ring NBR 70 is an industrial sealing material mainly used in the manufacturing of seals and waterproof materials. During use, it is necessary to pay attention to the correct installation method and usage environment to ensure its normal operation and extend its service life. In addition, for different application scenarios and operating conditions, it is necessary to choose different materials and specifications of O-rings to meet practical needs.
