ECTFE (HALAR^®)

ECTFE is a melt process able fluoropolymer, also known by the trade name Halar^®. The material’s chemical structure (a 1:1 alternating copolymer of ethylene and chlorotrifluoroethylene) makes it useful in a wide variety of applications, especially as a coating or lining.

ECTFE coatings offer excellent chemical and corrosion resistance over a wide temperature range of -76°C to 150°C. Good electrical properties, A tough material with excellent impact strength, ECTFE coatings maintains useful properties on exposure to cobalt 60 radiation at dosages of 200 megabrands. It is one of the best fluoropolymers for abrasion resistance.

Coatings will withstand full vacuum and high speed agitation. Our coatings are successful in many different chemical services, including caustics, acids, and organic solvents. The Thickness of the Coating 800 Microns to 1000 Microns will be maintained uniformly. We have Facility and coating Equipment to coat up to 20 kilo liters capacity vessels.

Applications of HALAR Coatings

• HALAR coatings are used to minimize wear in high frictional applications, where dimensional stability is a requirement.
• Typical applications include bearings, cams, valve seals, semi conductor tooling and cables.
• This coating can be used as bearing surface for machine tools.
• Can be used in electrical insulators due to high resistivity and low dielectric constant.
• Can be bonded by using the same type of epoxy resin or Ultra Sonics as other fluoropolymers.
• Chemical properties of HALAR coating resembles ETFE but with lower melting points.

HALAR Coatings are ideal for Chemical applications

HALAR is one of the most chemical resistant polymers that are available today. Some luminous characteristics of HALAR which meets the industrial demanding applications

• Excellent release properties
• Extremely smooth surface
• Dimensionally stable
• Low cold flow
• Ideal to operate at the temperatures (up to 300°F)
• Mechanically tough with excellent abrasion and impact resistance.
