  2. Polytetrafluoroethylene - Wikipedia

    en.wikipedia.org/wiki/Polytetrafluoroethylene

    Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally discovered the compound in 1938. [4]

    Also used in manufacturing badminton strings, bike tires and in electronics applications. Is the key component of a line of inflatable spacecraft developed by Bigelow Aerospace: Viton: Poly(vinylidene fluoride-co-hexafluoropropylene) Elastomer: Depends on the grade of the polymer. Viton B is used in chemical process plants and gaskets. Zylon

    en.wikipedia.org/wiki/Fluoropolymer

    In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett. While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a ...

    Not all non-stick pans use Teflon; other non-stick coatings have become available. For example, a mixture of titanium and ceramic can be sandblasted onto the pan surface, and then fired at 2,000 °C (3,630 °F) to produce a non-stick ceramic coating. [19] Ceramic nonstick pans use a finish of silica (silicon dioxide) to prevent sticking.

    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.

    Due to its high temperature resistance ETFE is also used in film mode as a mold-release film. [12] ETFE film offered by Guarniflon or Airtech International and Honeywell is used in aerospace applications such as carbon fiber pre-preg curing as a release film for molds or hot high-pressure plates. ETFE cushions roof with integrated photovoltaic ...

    Mild steel can be used for moderate vacuums above 1 × 10 −6 torrs (1.3 × 10 −7 kPa). Outgassing can be lowered with suitable (e.g. nickel) plating. It has high permeability to hydrogen and tendency to rust. For use it should be thoroughly degassed in vacuum. Aluminium and aluminium alloys are another class of frequently used materials.
