Chemical resistance was incorporated into ECTFE (ethylene chlorotrifluoroethylene) for heavy-duty corrosion applications. It’s a semi-crystalline partly fluorinated polymer (fluoropolymer) that may be treated in the melt. Chemically, it’s an ethylene-chlorotrifluoroethylene copolymer.
Many other fluoropolymer polymers are weaker, stiffer, and less dimensionally stable than ECTFE (ethylene chlorotrifluoroethylene). It has good electrical characteristics as well as a low coefficient of thermal expansion and minimal moisture absorption. When compared to other fluoropolymers, ECTFE (Halar®) has extraordinarily smooth surfaces, making it an excellent choice for many high-purity applications in the pharmaceutical and semiconductor sectors. Many softer fluoropolymers, such as PTFE, have lower strength, stiffness, abrasion resistance, and creep resistance than ECTFE.
