Performance Table of O-ring Material
O-ring is a commonly used sealing component, widely used in mechanical, automotive, aviation and other fields. Different application scenarios require the selection of different materials.
1. Fluororubber (FKM)
Fluororubber has excellent oil resistance, heat resistance, and chemical corrosion resistance, making it suitable for sealing requirements in harsh environments such as high temperature, high pressure, and high speed. But the price is high and not suitable for low-cost applications.
2. Nitrile rubber (NBR)
Nitrile rubber is a commonly used universal sealing material with good oil resistance, wear resistance, and aging resistance, suitable for sealing requirements at low temperatures, low pressures, and low speeds. But it is prone to hardening and aging in high temperature and high pressure environments.
3. chloroprene rubber (CR)
Chloroprene rubber has good oil resistance, cold resistance, and weather resistance, and is suitable for sealing requirements at low temperatures, low pressures, and low speeds. But it is prone to aging in high temperature and high pressure environments.
4. Butyl rubber (BR)
Butyl rubber has good elasticity and wear resistance, suitable for sealing requirements at low temperatures, low pressures, and low speeds. It may soften during high temperatures.
5. Ethylene propylene rubber (EPDM)
Ethylene propylene rubber has excellent oxidation resistance, ozone resistance, and weather resistance, making it suitable for sealing requirements in outdoor environments. But it is prone to hardening in high temperature and high pressure environments.
The above are common O-ring materials and their characteristics. Choosing the appropriate material can improve the sealing effect and service life.
