Halar® ECTFE is a partially fluorinated semi-crystalline polymer offering a unique combination of properties for highly demanding industries.
Halar® ECTFE is a melt-processable fluoropolymer that can be handled by conventional techniques such as:
Halar® ECTFE delivers outstanding chemical resistance, low permeability, excellent weatherability and good abrasion resistance. It is widely used in anti-corrosion applications as a lining or in self-supporting constructions (piping). Its excellent fire resistance properties and chemical resistance make Halar® ECTFE a product of first choice in wire and cable applications, in communication cable or specialty cable.
Halar® ECTFE purity, surface smoothness and chemical resistance, fire resistance are key characteristics in the semiconductor or PV market, for wet-tools constructions.
Halar® ECTFE films combine outstanding chemical, permeation and fire resistance properties, weathering and release properties.
The outstanding chemical resistance and strength of Halar® ECTFE has found wide acceptance in semiconductor and microelectronics, chemical processing, pharmaceutical and other challenging industries.
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.
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.
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.
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.
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.
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.
