Halar® ECTFE is a strong, highly impact-resistant, melt processible copolymer that retains its useful properties over a broad range of temperatures (cryogenic up to 300°F). ECTFE 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. ECTFE’s relative cost factor versus PTFE is approximately 2.25 to 1.
