Halar ECTFE is based on ethylene and chlorotrifluoroethylene. It offers outstanding chemical resistance over a broad temperature range and is stable at pH levels from 1 to 14.
 
Because of its exceptional chemical resistance, the material cannot be processed using solution phase inversion. Instead, it must be processed at temperatures close to its melting point (200 –240°C) using a TIPS process for hollow fibers. Two grades having different molecular weights and melt temperatures are available.

• Outstanding resistance to ozone and chlorine
• Stable at pH levels from 1 to 14
• Limited solubility in organic solvents
• Very good tensile properties
• Low level of extractible
• FDA compliance for selected grades
