The ECTFE resin is an alternating copolymer of ethylene and chlorotrifluoro-ethylene. It was
first commercialized by Allied Signal in 1974. The product was initially marketed for use in the chemical
processing industry due to its excellent chemical resistance, very low permeability to liquid and gases,
as well as very good strength and toughness at elevated temperatures. The industrial applications
include reactors, scrubbers, electrolytic cell liners, transport and storage tanks, tower packing, pipe,
and fittings exposed to very aggressive chemicals. Several of these structures have been used
successfully for more than 20 years in a variety of industries.
