Halar PV ECTFE is a semi-crystalline, melt-processable fluoropolymer resin that can be extruded into a highly transparent film (over 90% light transmission). It provides very good water vapor barrier (< 1 g/m2/day) in a wide range of temperatures and offers strong chemical resistance, good fire resistance, and long-term weatherability, making it suitable for 20-plus years of direct exposure to sunlight. It is an alternative to competing materials such as glass and other fluorinated polymers, offering greater fire resistance, higher tensile modulus, and lower density than its direct competitors.
In addition, Solvay has launched new Halar UV blocking technology which offers the same properties as Halar PV but also employs patented technology to deliver long-lasting UV blocking performance to meet the solar industry’s 25-year performance life for PV modules.
Solvay’s first partner in developing PV front sheet technology is Amcor Flexibles. Amcor is launching films based on the new Halar ECTFE technology for the PV front sheet market. Films are available up to 1.5 meters wide and 50 microns thick.
