The O-ring is a common sealing element that can be used in a variety of different applications, such as hydraulic system, sealing cavity, etc. Here are some common O-ring sealing materials:

1.Nitrile rubber (NBR): suitable for general industrial applications, oil resistance, solvent resistance, atmospheric aging resistance, ozone resistance and other performance is good.

2.Butyl rubber (IIR): has good resistance to oil and solvents, good air tightness and insulation, can be used to seal gasoline, oil and other substances.

3.Hydrogenated nitrile rubber (HNBR): has excellent corrosion resistance and tear resistance, outstanding performance in oil resistance, chemical resistance, can be used in automotive engine, washing machinery and other fields.

4.Silicone rubber (SIL): can resist the damage of cold, heat, ozone and atmospheric aging, poor tensile performance, not oil resistance, generally used in microwave oven, water heater, electric iron, water dispenser, kettle and other household appliances O-shaped sealing ring.

5.Fluorine rubber (FKM): with excellent high temperature resistance and chemical corrosion resistance, generally used in high temperature and chemical corrosion environment, such as fuel system and chemical plant O-ring.

6.Polyurethane (PU): with high mechanical strength and wear resistance, suitable for high pressure and high impact load applications.

7.Polytetrafluoroethylene (PTFE): with excellent chemical corrosion resistance and low friction coefficient, suitable for a variety of chemical media and high temperature environment.

8.Polyether etherketone (PEEK): with excellent high temperature resistance and corrosion resistance, suitable for requiring high temperature and chemical stability of applications.
