Polytetrafluoroethylene. Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. The commonly known brand name of PTFE-based composition is Teflon by Chemours, [1] a spin-off from DuPont, which originally discovered the compound in 1938.
Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads. Thread seal tape lubricates, allowing for a deeper seating of the ...
A convenient, safe method for generating TFE is the pyrolysis of the sodium salt of pentafluoropropionic acid: [6]. C 2 F 5 CO 2 Na → C 2 F 4 + CO 2 + NaF. The depolymerization reaction – vacuum pyrolysis of PTFE at 650–700 °C (1,200–1,290 °F) in a quartz vessel – is a traditional laboratory synthesis of TFE.
ETFE is a polymer and its source-based name is poly (ethene-co-tetrafluoroethene). It is also known under the DuPont brand name Tefzel and is sometimes referred to as 'Teflon Film'. ETFE has a relatively high melting temperature and excellent chemical, electrical and high-energy radiation resistance properties.
Thermoplastic. A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. [1][2] Most thermoplastics have a high molecular weight. The polymer chains associate by intermolecular forces, which weaken rapidly with increased ...
Xylan is the umbrella trademark for most of the Whitford Corporation fluoropolymer coatings line. Xylan is made of low friction, wear resistant composites of fluoropolymers and reinforcing binder resins. Xylan coatings can be one-, two- (primer and top-coat), and three- (primer, mid-coat, top-coat) coat conventional and reinforced (filled ...
