Fluoropolymer with outstanding mechanical properties and dimensional stability

ECTFE (ethylene chlorotrifluoroethylene) is stronger, stiffer, and more dimensionally stable than many other fluoropolymer materials. It exhibits excellent electrical properties, a low coefficient of thermal expansion, and low moisture absorption. ECTFE (Halar®) has exceptionally smooth surfaces compared with other fluoropolymers, which make it an ideal choice for many high purity applications in the pharmaceutical and semiconductor industries.

Tech TipECTFE has greater strength, stiffness, abrasion resistance, and creep resistance than many softer fluoropolymers such as PTFE.
