Halar® / ECTFE

  Technical Specifications

ECTFE (ethylene-chlortrifluorethylene), also known as Halar®, is a partially fluorinated semicrystalline polymer offering an array of mechanical properties and thermal and chemical resistance while also being easy to process. Halar® has excellent corrosion and chemical resistance and performs well in many applications at temperatures up to 300° F. It has excellent mechanical properties and extraordinary impact strength at temperatures ranging from -104° F to 302° F. Halar® is extremely low in permeability from liquids, gases and vapors. It is resistant to most corrosive chemicals, except for hot amines and ketones. The surface is very smooth and its purity is high. Halar® weathers well and is highly resistant to radiation. Typical applications include semiconductor process equipment, chemical storage, fluid handling, solid and lined pipe, tanks and tank linings, pump and valve components, components for wet-process stations, and centrifuge parts.
