Halar® (ECTFE) — Technical Data & End-Use Applications

Material Overview

Halar® (ECTFE - ethylene-chlorotrifluoroethylene) is a semi-crystalline fluoropolymer produced by Solvay. It offers superior chemical and corrosion resistance, excellent electrical insulation, and ease of processing—ideal for coatings, linings, and molded parts where durability in harsh environments matters.

Chemical & Environmental Resistance

Halar® resists a broad pH range (1–14), including strong acids, alkalis, oxidizers, and many solvents. It’s UV and weather-resistant and shows outstanding barrier performance in corrosive or clean environments.

Processing & Fabrication

• Available as powder for electrostatic coating, or as film/sheet/rod for extrusion, molding, or lining applications.
• Can be applied as thick film coatings (0.2–1.0 mm) with excellent surface evenness.
• Faster flowing and lower melting vs. ETFE—easier to apply coatings, though with a narrower bake window.

Typical End-Use Applications

• Chemical Processing Equipment: Linings and coatings for tanks, pipes, valves, reactors, plating racks, and storage vessels exposed to aggressive chemicals.
• Semiconductor Industry: Cleanroom ductwork and wet tool applications thanks to high purity, smooth surface, and fire resistance.
• Wire & Cable Jacketing: Used for specialty, high-performance cables requiring chemical/weather resistance and electrical insulation.
• Oil & Gas & Energy: Linings and coatings in corrosive environments, including H₂S resistance and PV module films due to optical clarity and UV stability.
• Architectural Films: Transparent, UV-stable films for tensile structures, membranes, and facades, often replacing glass in lightweight designs.
• Machined & Molded Parts: Pump housings, seals, containers, and aerospace-grade components.

Bottom line: Halar® ECTFE offers a superb balance of chemical resistance, mechanical durability, processability, and electrical performance—making it a top-tier thermoplastic solution for applications where PTFE is impractical and ETFE lacks abrasion or abrasion resistance.
