O Ring NBR
O-rings are mainly used for static clearance sealing of fluids (such as water, oil, air, chemical solvents, chemicals, etc.) The long-term service temperature is - 60 ℃ to 220 ℃. Depending on the material, the static service pressure is less than 20MPa. Sometimes it can also be used for dynamic, and the service pressure in dynamic is less than 5MPa. And semiconductor vacuum seal.
The commonly used materials are: nitrile rubber, silicone rubber, fluororubber and EPDM
Nitrile rubber, with a service temperature of minus 40 ° to 125 °, is resistant to mineral oil and has good wear resistance. It is most used in oil seals, but it cannot be used in ketone and lipid polar solvents.
There are more than 5000 models of nitrile rubber, with sufficient inventory:
