Ethylene-chlorotrifluoroethylene (ECTFE)
Description (definition)
Ethylene chlorotrifluoroethylene (ECTFE) is a semi-crystalline, thermoplastic fluoropolymer plastic known for its exceptional chemical resistance, high heat resistance and excellent mechanical properties. It is often used in demanding environments where high temperatures and aggressive chemicals occur, for example in the chemical industry, plant engineering and coating technology.
Example
A common example is the use of ECTFE as a protective coating for tanks and pipelines in chemical plants. The high corrosion resistance of ECTFE ensures that the infrastructure remains durable even in contact with concentrated acids and alkalis.
What are the most important properties of ECTFE?
ECTFE offers exceptional chemical resistance to acids, bases and solvents. It has high heat resistance up to 150 °C, low water absorption and excellent electrical insulation properties. These properties make it ideal for applications in extreme environments.
In which applications is ECTFE used?
ECTFE is used in the chemical industry for tank and pipe linings, in the electronics industry for cable insulation and in the coating of surfaces that need to be protected against corrosion. It is also used in medical technology and aviation, where reliability and durability are crucial.
How is ECTFE processed?
ECTFE can be processed by various methods, including extrusion, injection molding and coating processes. Due to its thermoplastic properties, it is relatively easy to mold and offers high precision in the production of components or coatings.
