Halar® ECTFE

A high-performance semi-crystalline fluoropolymer with a unique combination of properties.

What is Halar® ECTFE?

Halar® ECTFE is a partially fluorinated semi-crystalline polymer offering a unique combination of properties for highly demanding industries. It is widely used in anti-corrosion applications as a lining or in self-supporting constructions (piping). Its excellent fire resistance and chemical resistance properties make Halar® ECTFE a first choice in wire and cable applications. Halar® ECTFE offers purity, surface smoothness, chemical resistance, and fire resistance which are key characteristics in the semiconductor and photovoltaic markets.

Halar® ECTFE is an extremely pure polymer. Static soak testing in ultra-pure water and high purity chemicals shows extremely low levels of metallic and organic extractables. Additional dynamic rinse data validates Halar® ECTFE as suitable for high purity systems in the semiconductor, biotech, and pharmaceutical industries. Furthermore, Halar® ECTFE exhibits very low fluoride ion leach out.

For this reason, Halar® ECTFE is used as a lining and coating for ultra-pure water systems in the semiconductor industry. FM 4922 approved exhaust duct systems use Halar® ECTFE coated stainless steel.

One of the principal advantages of Halar® ECTFE fluoropolymer is the ease with which it can be processed. Halar® ECTFE fluoropolymer is a true thermoplastic that can be handled using the conventional techniques of extrusion as well as by blow, compression, injection, roto, and transfer molding. Halar® ECTFE polymer is available in a wide range of melt viscosities to suit virtually every processing technique.

Powder coating methods are also applicable. Halar® ECTFE is available in different grades that are specifically designed for electrostatic powder spray coating.

Electrostatic Powder Coating: generally, the procedure involves substrate preparation, spray coating, baking, and cooling. Several passes may be required to obtain the desired Halar® ECTFE load and build up coating thickness.

HALAR Coating Calculator

Instructions for use: This calculator will use specifications of the product to provide you with an estimated number of drums of material needed to complete your project.

Input the total square foot coverage of the project, estimated transfer efficiency, required total mil thickness to calculate.

Square Foot Coverage: Square feet of your part. Sq Ft = Length x Width.

Transfer Efficiency: A percentage (1-100%) that your powder will adhere to your part. This number is subjective. Keep in mind that at 100% transfer efficiency, you'd have zero waste / overspray.

Mil Thickness: This number determines how many "mils" or how thick your coating will be. Mils refers to 0.001 of an inch, not millimeters.

This calculator is for estimation purposes only.

Is Halar® ECTFE processable by solution coating?

What are the differences between Halar® ECTFE and ETFE?

ECTFE and ETFE are both partially fluorinated polymers. Their chemical difference resides in the chlorine atoms in ECTFE, which are substituted by a fluorine atom in the structure of ETFE. ECTFE and ETFE have similar chemical resistance, temperature rating, tensile properties, but ECTFE offers several advantages when compared to ETFE:

Higher tensile modulus

Harder surface

Better abrasion resistance

Superior fire resistance

Smoother surface

Better permeation resistance to water vapor and to gases such as oxygen, nitrogen, helium, carbon dioxide, chlorine, hydrogen chloride, hydrogen sulfide

What is better - Halar® ECTFE or fully fluorinated polymers like FEP or PFA?

No general answer can be given. When compared with fully fluorinated polymers like FEP or PFA, Halar® ECTFE offers much better permeation resistance to many chemicals. In corrosion protection applications like linings or coatings, this is even more important than chemical resistance, as the time to failure because of permeation (e.g. severe blistering or lining detachment) is often shorter than time for a chemical attack. Please seek advice on your specific application from your Solvay Specialty Polymers contact.

Do I need special equipment for processing Halar® ECTFE?

Halar® ECTFE is a melt-processable fluoropolymer that can be processed in the same way that conventional thermoplastics are processed. When processed by injection molding or extrusion, conventional three-zone single screw extruders can be employed, even if some peculiarities have to be taken into account. Processing recommendations are reported in the design guides for Halar® ECTFE.

Is it possible to pigment Halar® ECTFE to make it a different color?

Yes, it is possible. Halar® ECTFE â€“based masterbatches are readily available from major masterbatch suppliers like Colorant Chromatics, Clariant, Polyone, DainichiSeika, RTP and others. Should you need a resin matching a specific color rather than a color concentrate, please contact your Solvay Specialty Polymers contact.
