ECTFE stands for ethylene chlorotrifluoroethylene, a copolymer of ethylene and chlorotrifluoroethylene (CTFE). It is a partially fluorinated fluoropolymer known for its high chemical resistance and very low permeation. Unlike PTFE, ECTFE is melt-processable, so it can be extruded, injection moulded and welded.
Halar® is a brand name for ECTFE, now owned by Syensqo (formerly Solvay). The two names are often used interchangeably, but ECTFE is the material and Halar® is one brand of it. Polyfluor has supplied ECTFE for more than 40 years.
ECTFE can be used continuously from −75 °C to +150 °C and briefly up to 180 °C, with a melting point of 240 °C. It combines high resistance to acids and oxidising agents with very low permeation, excellent weather and radiation resistance, and good electrical insulation (dielectric strength 40 kV/mm). All values are listed in the ECTFE datasheet.
ECTFE is mainly used where aggressive chemicals cause corrosion, for example in hoses, piping and coatings for chemical handling. Key industries include oil & gas/petrochemicals, semiconductors, medical, aerospace and electronics. Check suitability for your medium in our chemical resistance chart.

A line carrying acid, chlorine or hypochlorite discolours, stiffens or starts to "sweat". Or the medium picks up contamination from the line itself. In many of these cases, the root cause is the material. In this article you will learn when ECTFE tubing is the right solution, when another fluoroplastic is a better fit, and which data you need for a complete enquiry.
ECTFE has a strong reputation for resisting acids, alkalis and oxidizing agents. But ECTFE chemical compatibility is never absolute. This article explains what ECTFE resists, where its limits are and how to read a chemical resistance chart correctly, so you can run a first suitability check yourself.
ECTFE vs ETFE is a comparison that looks straightforward on paper. Both are fluoropolymers with similar names, similar densities and the same melt-processability. In service, however, they behave quite differently – especially with oxidising media or when permeation is critical.
Tanks, pipes and scrubbers made of carbon or stainless steel will corrode sooner or later when they handle acids or oxidizing media. An ECTFE coating keeps the medium away from the metal altogether. A fluoropolymer coating can still fail, though, when material selection, surface preparation or inspection fall short.This article explains when a protective layer of ECTFE is the right choice, how it is applied and which factors decide its service life.
You order ECTFE film for a chemical barrier layer, or ECTFE sheet for a process tank wall. The part looks right on delivery, but a week later the dimensions have drifted. Or a weld seam that looked clean cracks during the first heat-up cycle. In most cases, the material is not the problem. The cause lies in the choice of form or in the way it was processed. This article explains which form suits which application and which properties determine processing.
