PTFE –polytetrafluorethylene – is unique in its extraordinary properties.
It is commonly known under the brand names Téflon®, Hostaflon®, Algoflon® and Fluon®.
High resistance to high and low temperatures (+260° C in continuous operation), thanks to a 327°C melting point, non-combustible and a good heat insulator.
Extremely low coefficient of friction, anti adhesive and non-wettable surface, wear resistance adapted with the addition of fillers such as glass, carbon or graphite.
Excellent chemical resistance to all products (except molten alkaline metals and certain highly reactive fluorinated agents), no moisture absorption and good weather resistance.
Physiologically inert and innocuous for food.
Good electrical insulator, with high surface resistivity, good resistance to electric arcs and very low electric losses.
Certain PTFE properties can be improved by mixing pure PTFE powders and certain fillers such as glass, graphite, carbon, bronze, stainless steel, mos², ceramics, calcium fluoride, ekonol, nickel and metal oxides: VX1 and Rulon®, etc.
