ECTFE (ethylene chlorotrifluoroethylene) is stronger, stiffer, and more dimensionally stable than many other fluoropolymers. It exhibits excellent electrical properties, a low coefficient of thermal expansion, and low moisture absorption. ECTFE (Halar®) is abrasion, chemical, and weather resistant, with excellent fire resistance, and exhibits low levels of metallic and organic extractables.
Compared with other fluoropolymers, ECTFE has exceptionally smooth surfaces and is an ideal choice for many high purity applications in the semiconductor and pharmaceutical industries. Please ask your Curbell Plastics representative for more specific information about an individual brand.
