ECTFE MATERIALS (Ethylene Chlorotrifluoroethylene)
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.
ECTFE IS WIDELY USED FOR:
- Linings for tanks, vessels, and reactors
- Semiconductor and pharmaceutical chemical storage tanks and ductwork
- Piping systems / fluid processing components
- Exhaust hoods
- Electroplating equipment
- Stronger and stiffer than many other fluoropolymers with high impact strength
- Excellent electrical properties
- Abrasion, chemical, and weather resistant
- Exceptionally smooth surfaces
- Low levels of metallic and organic extractables
- Excellent fire resistance
