What is Ethylene-chlorotrifluoroethylene? (ECTFE)

July 2016


Ethylene-chlorotrifluoroethylene- Chemical Compound (ECTFE)

Ethylene-chlorotrifluoroethylene  (ECTFE) is a partially fluorinated semi-crystalline polymer developed for chemical resistance and introduced in 1970.

ECTFE is sold under various brand names, Halar® being the most popular; it is a melt-processable Fluoropolymer that can be handled by conventional techniques such as:

  • Compression molding
  • Injection molding
  • Extrusion

Our Fluorinoid® FL346, virgin ECTFE has high purity, chemical resistance and fire resistance making it ideal in the semi-conductor market.

ECTFE is vastly superior in coating applications requiring chemical resistance in corrosive applications.

Fluorocarbon Surface Technologies, part of the Fluorocarbon Group can also provide F-LON® 7000 as a standard coating and F-LON 7070® as an FDA compliant coating. Other application-specific coatings are available offering chemical and corrosion resistance over a wide temperature range, typically -50°C to +150°C for more information click here

Key features are:

  • Excellent Chemical resistance
  • Excellent resistance to ozone, sunlight, and weather
  • Low dielectric constant and high dielectric strength
  • Very low permeation value
  • Radiation resistance
  • Surface smoothness

Another benefit of ECTFE is weldability; resistance, infrared and hot gas welding are all possible. It also has excellent machinability, allowing for easier fabrication of components.

Typical applications include:

  • Oil & Gas- Insulated wire, chemical storage equipment, control line encapsulation and other Coatings.
  • Semi-conductor- Tooling, wire and cable, bearings and valve seats.
  • Food and Beverage- Air and gas filters
  • Automotive- Fuel management, wire insulation, O-rings, diaphragms, and seals.
  • Chemical processing- Piping systems for aggressive chemicals, coating of storage vessels,
