Perfluoralkoxy (PFA)
Like PTFE, perfluoralkoxy polymers are fully fluorinated hydrocarbons. Whereas PTFE can only be processed by sintering, perfluoroalkoxy can be processed by the usual thermoplastic methods such as injection moulding and extrusion at high temperatures.
Perfluoroalkoxy plastics are very resistant to high temperatures (melting point 310 °C) and, like PTFE, resistant to almost all chemicals. They are therefore mainly used in laboratory equipment such as hoses, containers, pump components and connecting elements.
PFA are not wettable, not adhesive and not printable. By means of plasma etching, however, they can be activated to be made fit for all these processes.
