Halar® Applications

Chemical

Containers; diaphragms; protective linings/coatings for tanks, pumps, valves, pipes, scrubbing towers, reactors, thermocouple wells, centrifuge components; heat exchangers, ducting, unsupported pipe and tubing; tower packing; valve seats; filters; dust collectors; mist eliminators; closures; filter fabric; fittings; process system components.

Coatings

Agitators; centrifuges; containers; hoods; membranes; filters; pumps; vessels; reactors; piping systems; caustic collectors; semiconductor chemical storage tanks; electroplating equipment.

Cryogenic and Aerospace

Pump liners; seals; gaskets; valve seats; fittings; gaskets for liquid oxygen and other propellants; components for manned space vehicles and aircraft cabins, space suits.

Medical

Solvay Solexis does not recommend the use of Halar® fluoropolymer for medical applications.

Custom Processing

Halar®-lined glove box for the processing of radioactive materials, high purity pharmaceuticals or semiconductor devices. Halar® fluoropolymer provides excellent chemical resistance, ease of fabrication, and easy cleaning.

Oil and Gas

Ideal material for use in the oil and gas industry due to its good mechanical properties and excellent chemical resistance to a wide variety of organic and inorganic chemicals, even at elevated temperatures. The tough, resistant Halar® fluoropolymer coating extends the life of many down hole components in harsh well environments.

Semiconductor/High Purity

Clean room, fire-safe plastics- Halar® and Clear Halar® ECTFE are approved materials for fire-safe wetbenches and wafer processing equipment. The use of these materials eliminates the need for fixed fire suppression in this equipment.

Other successful applications include DI water high purity processing systems; chemical handling systems including unsupported and supported piping, tanks, and vessels. Factory Mutual Approved for fume and smoke exhaust ductwork with a longer service life than stainless steel. Powder coated surfaces of Halar® fluoropolymer exhibit extraordinary smoothness as measured by SEM and AFM analytical methods. Halar® ECTFE has superior chemical resistance and high temperature resistance up to 150°C (300°F).

Food Processing

Available in FDA 21 CFR 177.380(a)(4) compliant grade.

Additional Halar® Information

  • Excellent resistance to strong acids, such as sulfuric, nitric, hydrochloric, and hydrofluoric, over a wide temperature range.
  • Easily handles powder-bleaching agents, such as sodium hypochlorite.
  • Resists strong bases, such as sodium hydroxide, that would stress crack PVDF.
  • Resists strong polar solvents, such as n-Methyl pyrrolidone and dimethylformamide that would dissolve PVDF.
  • Not dissolved by any known solvent to 300°F.
  • Best radiation resistance of all fluoropolymers.
  • Ozone-resistant.
  • Halar® is recommended for high purity fluid systems in semiconductor and other industries.
