Halar® ECTFE Applications

The outstanding chemical resistance and strength of Halar® ECTFE has found wide acceptance in semiconductor and microelectronics, chemical processing, pharmaceutical and other challenging industries.

Architectural Membranes

High performance films made of Halar® ECTFE are widely used as architectural membranes, thanks to their unique properties:

  • Transparent & Light – Halar® ECTFE film is lightweight and provides excellent light transmittance
  • Superior Durability – Maintains transparency and strength for around 20 years. Also highly resistant to fire and high heat.
  • Self-cleaning – Dust and dirt does not settle on Halar® ECTFE easily. However, if it does, minimal rain or water will clear the surface of dirt and grime
  • Eco-friendly - Some thermoplastic films are recyclable and decrease energy costs by around 30% when compared to glass, due to their capacity to allow in more natural light and their heat retention properties.

Chemical Processing Industry (CPI)

Halar® ECTFE offers its excellent chemical and permeability resistance to CPI applications including: High performance coatings; Filtration & separation; Pump diaphragms and filter components; Gas separation membranes; Linings; Fluid and gas handling applications.

Frontsheet Films

Halar® ECTFE films are UV stable and optically clear with more than 90% transmission of light in the visible spectrum, while combining excellent fire resistance properties with very good mechanical performance. Halar® ECTFE films exhibit significantly lower permeation rate to water vapor than ETFE. PV modules made with Halar® ECTFE film are exceptionally durable and meet the toughest industry requirements.

Membranes

Halar® ECTFE offers outstanding chemical resistance over a broad temperature range and is stable at pH levels from 1 to 14. Because of its exceptional chemical resistance, the material cannot be processed using solution phase inversion. Instead, it must be processed at temperatures close to its melting point (200 –240°C) using a TIPS process for hollow fibers. Two grades having different molecular weights and melt temperatures are available.

Protective Linings

Protective linings in piping, tanks and other vessels fabricated with Halar® ECTFE provide excellent resistance to extreme chemicals and temperatures. Lining options include sheet lining, extruded lining, rotational lining, powder coating or FRP dual laminate.

Semicon

Halar® ECTFE delivers exceptional results in semiconductor environments. It is used as a coating and/or lining material in exhaust duct, vessels and process equipment. Halar® ECTFE powder coatings have been used successfully for fire safety and corrosion protection of exhaust duct systems that must meet the FM4922 fire safety standard. Halar® ECTFE coated ductwork offers exceptional surface smoothness reducing the risk of contamination buildup and corrosion.

Case Studies

Fluoropolymers are often a better choice than metals for vessels and pipes exposed to corrosive environments. Halar® ECTFE has proven to be an effective solution for process engineers and specifiers in search of long-term chemical, temperature, corrosion and permeation resistance.

Halar® ECTFE stack liner

Halar® ECTFE-lined chimney remains maintenance-free
After 15 years, a fiberglass-reinforced FRP/Halar® chimey liner is still in good working order without any repairs. The chimney is part of a power station in the North Jutland region of Denmark. The liner is exposed to sulfuric acid at 110°C. Recent inspections showed no signs of chemical attack by the exhaust gas and no surface cracking was observed.

Chlorine scrubber

Fluoropolymer lining for a chlorine scrubber
An FRP/Halar® ECTFE dual laminate chlorine scrubber installed in a petrochemical plant delivered continuous service for 14 years.  After the plant was shut down, the liner was inspected and found to be in excellent condition despite its exposure to chlorinated hydrocarbons combined with hydrochloric acid and molecular chlorine.

Fluoropolymer-lined process vessel

Long-term performance of a fluoropolymer-lined process vessel
A Halar® ECTFE-lined holding tank was undamaged after 23 years of service. It handled alkaline-based fluids and active chlorine in a vinyl chloride monomer plant.
