Properties of ECTFE
- It is a copolymer of ethylene and chlorotrifluoroethylene.
- ECTFE resin is tough, medium hardness and creep resistance.
- The operating temperature is -100°C to +150°C (-148°F to +302°F).
- The melting temperature depends on the monomer ratio in the polymer and ranges from 235°C to 245°C (455°F to 473°F).
- ECTFE has excellent weather resistance.
- ECTFE can resist high-energy gamma and beta radiation up to 100 Mrad (1000 kGy).
- The largest single application of ECTFE is as the primary insulation and sheath of voice and copper cables used in building ventilation systems.
- In automotive applications, ECTFE is used for cable sheaths of liquid level sensors in fuel tanks, connecting wires and heating cables for car seats.
- In the chemical processing industry, it is commonly used in chlorine/corrosive environments in electrolytic cell covers, outlet boxes, lined pipes, and storage tanks.
- In the pulp and paper industry, ECTFE is used to line bleaching agents and scrubbers.
- Monofilaments made of ECTFE are used for chemically resistant filters and screens.
- Other applications include rotomolding tanks and containers for storing corrosive chemicals such as nitric acid or hydrochloric acid.
- ECTFE film is used as a separator in the manufacture of high-temperature composite materials for aerospace applications.
- Thanks to its resistance to most organic solvents, ECTFE membranes can be used for separation of organic/organic mixtures by pervaporation.
