Introduction ECTFE Semi-Finished Products
Ethylene Chlorotrifluoroethylene (ECTFE), often known by the brand name Halar®, is a semi-crystalline fluoropolymer that combines excellent chemical resistance with good mechanical properties and low permeability to gases and vapors. While sharing the chemical inertness of other fluoropolymers like PTFE, ECTFE surpasses them in terms of mechanical strength and barrier properties. This makes ECTFE semi-finished products particularly valuable in applications where preventing chemical permeation and maintaining structural integrity under stress are critical. This article explores the key properties of ECTFE and highlights its essential role in demanding chemical processing and containment applications.
Core Properties of ECTFE
- Outstanding Chemical Resistance: Highly resistant to a vast range of chemicals, including strong acids, bases, oxidizing agents, and solvents. Comparable to PTFE in chemical inertness.
- Superior Permeation Resistance: Among fluoropolymers, ECTFE exhibits exceptionally low permeability to gases and vapors, making it ideal for containment applications.
- Good Mechanical Properties: Better tensile strength, impact resistance, and creep resistance compared to PTFE and other fluoropolymers, especially at elevated temperatures.
- Thermal Stability: Continuous service temperature up to approximately 150°C (302°F).
- Low Flammability: Self-extinguishing properties with low smoke emission.
- Radiation Resistance: Good resistance to ionizing radiation.
- Processability: Can be melt-processed (extruded, injection molded) and converted into various semi-finished forms.
