PTFE is the chemically inert of the O-ring materials. 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.
PTFE is a specially important engineering plastic because of its outstanding lack of friction and slippiness, this is so incredibly low that is has been described as being the slippiest solid material known to man. PTFE is also highly specified due to its very high temperature resistance allowing components to withstand almost double that of other types of engineering plastic. PTFE has the capability to also withstand very strong acids and chemicals helping to provide solutions to acid storage and chemical problems. High electrical resistance is yet another feature of PTFE and PTFE is often used in high end electrical resistance appliances. PTFE also has excellent acid and chemical resistance. Another feature of PTFE is its ability to set by or due to compression. PTFE is also water repellent and is often used in the manufacture of modern high performing, water repellent and breathable clothing.
