Release time:
2024-04-26
O-ring is a common sealing element, which can be used in various applications, such as hydraulic systems, sealing chambers, etc. The following are some common O-ring materials: 1. Nitrile rubber (NBR): suitable for general industrial applications, oil resistance, solvent resistance, atmospheric aging resistance, ozone resistance and other good performance. 2. Butyl rubber (IIR): It has good resistance to petroleum and solvents, good air tightness and insulation, and can be used to seal gasoline, engine oil and other substances.

2. Butyl rubber (IIR): It has good resistance to petroleum and solvents, good air tightness and insulation, and can be used to seal gasoline, engine oil and other substances.
3. Hydrogenated nitrile rubber (HNBR): It has excellent corrosion resistance and tear resistance, outstanding performance in oil resistance and chemical resistance, and can be used in automobile engines, washing machinery and other fields.
4. Silicone rubber (SIL): It can resist the damage of cold, heat, ozone and atmospheric aging, and has poor tensile properties and is not resistant to oil. It is generally used for the O-ring of household appliances such as microwave ovens, water heaters, electric irons, water dispensers, kettles, etc.
5. Fluorine rubber (FKM): It has excellent high temperature resistance and chemical corrosion resistance. It is generally used in high temperature and chemical corrosion environments, such as O-rings in fuel systems and chemical plants.
6. Polyurethane (PU): with high mechanical strength and abrasion resistance, suitable for high pressure and high impact load applications.
7. Polytetrafluoroethylene (PTFE): It has excellent chemical corrosion resistance and low friction coefficient, and is suitable for various chemical media and high temperature environments.
8. Polyetheretherketone (PEEK): It has excellent high temperature resistance and corrosion resistance, and is suitable for applications requiring high temperature and chemical stability.
