ECTFE

ECTFE

ECTFE (Ethylene chlorotrifluoroethlyene) is a fluorocarbon-based polymer (a fluoropolymer), a kind of plastic. It is marketed under the brand name Halar ECTFE by Solvay Solexis. Solvay Solexis is the only producer of Halar.

Physical and chemical properties

It offers high impact strength, chemical and corrosion resistance over a wide temperature range — typically -76°C to +150°C (-105°F to +300°F). It has high resistivity and low dielectric constant.

Applications

ECTFE is used to minimize wear in high-friction applications, where dimensional stability is a requirement.

Some typical applications include bearings, cams, valve seats, semiconductor tooling and wire and cable. It is used as a bearing surface for machine tool ways. It is also used in electrical insulators due to its high resistivity and low dielectric constant.

ECTFE is commonly available as sheets, bars, and rods. It may be bonded using the same type of epoxy resin as other fluoropolymers.
