ECTFE

ECTFE – Ethylene chlorotrifluoroethylene – is a less popular material, but features characteristics that no other thermoplastic can achieve. As a copolymer, its molecular chain contains, in a repetitive fashion, one ethylene element followed by one chlorotrifluoroethylene element: thanks to this structure, ECTFE – Ethylene chlorotrifluoroethylene – is physiologically applicable without limitations, resists high temperatures of up to 150°C also for extended periods, and is one of the most resistant thermoplastic against irradiation and weather conditions. The high resilience of this material mixes with good mechanical strength: values do not vary greatly in the entire temperature range. The smooth surface of the components of this material is no base for the growth of microbiological fauna, so it can be used in the food and microchips manufacturing industries. This material, like also other thermoplastics, is easy to weld and work.

The fire resistance rating is V-0 according to UL 94 standard, so, this material is ranked as self-extinguishing.

The ECTFE line includes fittings and pipes from OD 20 mm to OD 110 mm in NP 10, diaphragm valves from ND 15 mm to ND 50 mm NP 10 according to UNI EN ISO 16138 standard and semi-finished products like sheets, welding rods and round bars.

ECTFE can be welded with the butt joint procedure, by direct contact, or by irradiation with manual or automatic welding machines.
