Applications
Commonly known as Teflon, PTFE resists high temperatures and chemicals/solvents excellently in and is also a great insulator. It is also a very slippery plastic, which makes it a good material for low-friction applications such as bearings.

Cost Saving Tip
To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
Can PTFE be machined?
Yes, PTFE (commonly known as Teflon) is a very slippery plastic, which makes it a good material for machining low-friction parts such as bearings. PTFE resists high temperatures and chemicals/solvents making it an excellent insulator.
Is ptfe rubber or plastic?
Polytetrafluoroethylene (PTFE) is a thermoplastic.
What are the advantages and disadvantages of PTFE?
The advantages of PTFE (polytetrafluoroethylene) include:
The disadvantages of PTFE include:
What is PTFE used for?
PTFE applications range from non-stick coating in kitchen cookware to high-tech medical and hospital uses including implants, surgical instruments and test equipment.
PTFE is highly heat resistant and resists friction against solids, which enables PTFE to be used as a component of gears, gaskets, side plates and bearings. It’s also used to make containers and pipes because it is anti-corrosive, and non-reactive. PTFE also has good electric insulation properties and is used in insulating cables and connector assemblies. This makes it ideal for coaxial cable, printed circuit boards and hookup wire.
