Polytetraflourothylene (PTFE) is a low friction fluoropolymer with excellent resistance to chemicals and the elements.
PTFE has many applications however, thanks to its waterproof and low friction properties. Its most common industrial application is in the manufacture of pipework , seals , and containers carrying corrosive or reactive chemicals. PTFE plastics can also be used to lubricate machinery and can vastly reduce friction and improve the general wear and energy efficiency of the equipment.
PTFE also has excellent resistance to high temperatures. Most other elastomers and plastics can only withstand temperatures up to 77 degrees whereas PTFE can withstand temperatures as high as 280 degrees.
The chemical inertness of PTFE refers to its ability to be in constant contact with another substance without a chemical reaction occurring. Of course, this does not apply to all substances, and test data varies - absorption and chemical reactions will differ depending on the substance in question.
Thanks to their low friction properties, PTFE is used for applications where sliding parts are used. This might include gears, bearings and slide plates in machinery and other components. In tests and in industrial applications, PTFE has been found to perform significantly better than other plastic types.
PTFE is used in many industrial and commercial applications, including:
