|A fluoropolymer is a Polymer that contains atoms of fluorine. It is characterized by a high resistance to solvents, acids, and bases.|
Fluoropolymers were discovered serendipitously in 1938 by Dr. Roy J. Plunkett. He was working on freon (for the DuPont corporation) and accidentally polymerized tetrafluoroethylene. The result was P.T.F.E. (polytetrafluoroethylene), more commonly known as Teflon. This material had the lowest coefficient of friction of any known solid and was inert to virtually all chemicals.
Examples of fluoropolymers:
P.T.F.E. polytetrafluoroethylene, e.g. Teflon
P.F.A. perfluoroalkoxy Polymer resin, e.g. Teflon
F.E.P. fluorinated ethylene-propylene, e.g. Teflon
E.T.F.E. polyethylenetetrafluoroethylene e.g. Tefzel, Fluon
P.V.F. polyvinylfluoride e.g. Tedlar
E.C.T.F.E. polyethylenechlorotrifluoroethylenee.g. Halar
P.V.D.F. polyvinylidene fluoride e.g. Kynar
P.C.T.F.E. polychlorotrifluoroethylene, e.g. Kel-F, CTFE
F.F.K.M. e.g Kalrez, Tecnoflon, FFKM
F.P.M. / F.K.M. e.g. Viton, Tecnoflon
P.F.P.E. Perfluoropolyether e.g. Fomblin, Galden
Fluoropolymers may be mechanically characterized as Thermosets or thermoplastics. They are often applied to manufactured metal parts by electrostatic powder coating, or attached in large sheets with epoxy to line the interior of large metal and non-metal containers.
Apex GB have over 20 years experience in manufacturing Plastic & Rubber Extrusions, Extruded Profiles and Tubing. We're quite rightfully proud of our reputation for consistently meeting the needs of customers over that time. Because we've remained small and focussed we've also remained more attentitive, more cost effective and more responsive than larger manufacturers.
