PTFE - polytetrafluoroethylene
Polytetrafluoroethylene (abbreviation PTFE, also called polytetrafluoroethene) is a linearly structured, unbranched, partially crystalline polymer of fluorine and carbon.
Known under the trade name Teflon™ by DuPont. Other trade names for PTFE include Dyneon PTFE (formerly Hostaflon) and Gore-Tex for PTFE membranes. PTFE belongs to the class of polyhaloolefins; it is a thermoplastic, although it also exhibits properties that necessitate processing more typical of thermosetting plastics. Teflon™ is a nonpolar polymer. PTFE is not a byproduct of aerospace. It was discovered in 1938 by chemist Roy Plunkett while experimenting with tetrafluoroethylene (TFE) in his search for refrigerants for refrigerators. PTFE is produced from chloroform (CHCl3) through partial fluoridation. PTFE is very unreactive. Even aggressive acids like aqua regia cannot attack it. PTFE has a particularly strong bond between the carbon and fluorine atoms. Many substances are unable to break these bonds and react chemically. Due to its chemical inertness, PTFE is used, among other things, as a corrosion protection coating . Its coefficient of friction is very low. PTFE slides on PTFE almost as easily as wet ice on wet ice. In sealing technology, PTFE is used as a base compound in many applications. It is also used as a lining material in chemical plant construction . Because of its low friction, PTFE is used as a dry lubricant.
Rhenotherm Kunststoffbeschichtungs GmbH carries out contract coatings with PTFE ( PTFE coating ) and is certified as a contract coater according to DIN EN ISO 9001:2015.
