ECTFE possesses a unique combination of properties that are the result of its chemical structure, which consists of a copolymer with ethylene and chlorotrifluoroethylene arranged alternately. ECTFE demonstrates excellent resistance to the corrosive influence of heat, strong radiation, and weathering. The material has high impact resistance and shows almost no property changes in a wide temperature range, making it particularly well-suited for demanding industrial applications. Furthermore ECTFE is known for its good permeation barrier for many chemicals. Its excellent welding properties and thermoplastic formability also make simple and cost-saving processing possible, both in the workshop and on-site. Compared to PVDF, ECTFE has a better chemical resistance, especially when exposed to lyes.
