Halar® ECTFE Coating

This coating is a strong, highly impact-resistant, melt-processible copolymer that retains its useful properties over a broad range of temperatures (cryogenic up to 149°C (300°F)). ECTFE (Ethylene-ChloroTriFluoroEthylene) exhibits excellent electrical properties, low moisture absorption, and temperature insensitivity, making it a material of choice for plenum-rated wire and cable jacketing.

ECTFE is distinguished from other fluoropolymers by its exceptional surface smoothness. In addition to electrical components, ECTFE works well for high-purity processing components for the chemical and semiconductor industries.
