The ECTFE film is strong and tough and has great abrasion resistant properties, which makes it even suitable for desert areas. Furthermore it has excellent water vapour barrier properties in a wide temperature range of -200°C to +165°C.
“Compared to conventional ETFE films, the barrier is up to five times better,” said Raymond van Faassen, global market manager at Amcor Flexibles Europe & Americas. “Thanks to the film’s special, highly transparent, primer technology, it is also possible to increase the bond strength with other substrates, a task not easily done due to its fluoropolymer low surface tension characteristic.
The ECTFE film has a LOI (Limiting Oxygen Index) of more than 51%, indicating that an oxygen concentration of at least 51% is required to support the combustion process. This results in outstanding fire resistance properties and an auto ignition temperature of more than 655°C.
Currently Amcor Flexibles has two types of films in the portfolio: a standard ECTFE film and a UV-blocking film available in different thicknesses and widths.
