Material FEPGlossaryFEPTetraflouroethylene-Perflouropropylene – Tetrafluoroethylene-Perfluoropropylene

A molten copolymer of tetrafluoroethylene and perfluoropropylene with a high-molecular, partly crystalline structure which was introduced on the market in 1960. Its mechanical and chemical properties are comparable with those of PTFEGlossaryPTFEPolytetrafluoroethylene , however, the upper limit of the permanent working temperature is lower than that of PTFEGlossaryPTFEPolytetrafluoroethylene  (max. +205 °C). FEPGlossaryFEPTetraflouroethylene-Perflouropropylene is a typical thermoplastic material which can be treated and machined by using established methods, although its high viscosityGlossaryviscosity Degree for the resistance of a liquid against flowing.  limits the speed of operation. FEPGlossaryFEPTetraflouroethylene-Perflouropropylene labware is translucent to transparent and non-porous.
