Material FEP – 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 PTFE, however, the upper limit of the permanent working temperature is lower than that of PTFE (max. +205 °C). FEP is a typical thermoplastic material which can be treated and machined by using established methods, although its high viscosity limits the speed of operation. FEP labware is translucent to transparent and non-porous.
