ECTFE is an engineering thermoplastic fluoropolymer used as a material for coating applications. It is known under the trade name HALAR®.

ECTFE coatings are often chosen for applications where the greatest chemical resistance is required, including operating at high temperatures. Its excellent corrosion-resistant properties provide protection from most ultrapure chemicals, strong inorganic bases, acids and organic solvents. It is widely used in the chemical processing, oil and gas and pharmaceutical industries.
