PCTFE Polychlorotrifluoroethylene PCTFE, Polychlorotrifluoroethylene (fluteck™ C100) is a melt-processable chlorofluoropolymer: the presence of a chlorine atom, which has a greater atomic radius than that of fluorine, gives rise to irregularities in the polymer chain and reduces polymer crystallinity. This results in PCTFE having a relatively low melting point among fluoropolymers. It is also the polymer with the lowest water vapor and moisture absorption rate. It resists ignition because its Limiting Oxygen Index (LOI) is greater than 95. PCTFE resists attack by most chemicals, a property that is exhibited due to the presence of its high fluorine content. It is oxidation resistant because it does not have any hydrogen atoms. The main field of application of PCTFE is cryogenics due to the fact that it is the fluoropolymer that best retains its mechanical properties at extremely low temperatures and is therefore the least fragile of the fluoropolymers. PCTFE is incompatible with alkaline metals and in some cases with organic amines. Its use is not recommended at temperatures above 150°C. fluteck™ C100 Comparison Table FLON GASKETS S.R.L. – 24060 Sovere (BG) Italy – Via delle Industrie 7 – Phone +39 035 827119 – Fax +39 035 827243 – VAT n° IT03811300163 We use cookies to ensure that we give you the best experience on our website.
