PTFE O Ring is a popular material which used in chemical resistant and non-compressible applications.Pure PTFE O Ring is white color.
Polytetrafluoroethylene (PTFE) is used wherever the chemical and thermal resistance of the elastomer O-Rings is no longer sufficient. These are primarily applications in the chemical, food, pharmaceuticals and medical industries. PTFE is used only as static seals, e.g. on flanges, covers, etc.
PTFE has the highest resistance to chemicals of all the plastics and can be used for almost any application. It has limited resistance to molten alkaline metals, to elementary fluorine and to certain halogen compounds. PTFE undergoes no changes on exposure to aging, light and ozone. The water absorption rate is less than 0.01%.
It is resistant to most chemicals including acids, bases, oils, steam and other chemicals. It is also very tough and abrasive resistant. However the material is not easily compressed, and therefore may not seal as easily as some of the other polymers. Its outstanding tear resistance and abrasive resistance result in its slippery surface properties that make it advantageous for use in seals in moving systems such as mass spectrometer probes and valves.
