ECTFE – Ethylene chlorotrifluoroethylene

Ethylene chlorotrifluoroethylene (abbreviated ECTFE) is a thermoplastic fluoropolymer that provides excellent chemical resistance, good electrical properties, a broad-use temperature range. It is a tough material with excellent impact strength and wear resistance.

ECTFE was first produced by Allied Chemicals (Halar®) at the same time as ETFE and the mechanical properties are very similar to those of ETFE. ECTFE also has mechanical properties approaching those of fully fluorinated polymers, with a lower maximum service temperature and the lowest density.
