May 2, 2014 - Able to be extruded into transparent film with over 90% light transmission, Halar® PV ECTFE semi-crystalline, melt-processable fluoropolymer resin provides water vapor barrier (<1 g/m˛/day) as well as chemical and fire resistance. Product offers long-term weatherability and is suitable for 20+ years of direct exposure to sunlight. In addition to properties as Halar PV, Halar UV blocking technology provides long-term UV blocking performance to meet 25-year performance life for PV modules.

Solvay Unveils New Halar® ECTFE Film Grades for Production of Front Sheets for Photovoltaic Modules

Press release date: April 24, 2014

New Materials Expand Solvay's Market Position in Solar Industry

BRUSSELS -- Solvay Specialty Polymers has launched two new film grades of Halar® ethylene chlorotrifluoroethylene (ECTFE) that are specifically designed for front sheet applications for photovoltaic (PV) modules. Halar® PV ECTFE and Halar® ECTFE UV blocking technology mark Solvay’s entrance into PV front sheet applications. The new products complement Solvay’s extensive material offering for PV modules which includes Solef® polyvinylidene fluoride (PVDF) and Halar® ECTFE for back sheets and Cogegum® XLPO HFFR for cables and Polidiemme® XLPO for innovative encapsulants.

The new film grades for front sheets expand Solvay’s penetration of the growing PV module market where it is already a key supplier of Solef® PVDF and Halar® ECTFE for PV back sheets. “With our broad product portfolio we are firmly positioned as a strategic supplier to the global PV market and this new launch signals our further commitment to the industry,” said Philippe-Jacques Leng, global market manager for film for Solvay Specialty Polymers. “We believe this is a highly sustainable market that requires specially designed materials to meet the PV industry’s high-performance needs.”

Halar® PV ECTFE - a semi-crystalline, melt-processable fluoropolymer resin - can be extruded into a highly transparent film (over 90% light transmission). It provides excellent water vapor barrier (< 1 g/m2/day) in a wide range of temperatures and offers strong chemical resistance, exceptional fire resistance, and long-term weatherability, making it suitable for 20-plus years of direct exposure to sunlight.

Halar® PV ECTFE is a highly viable alternative to competing materials such as glass (rigid, heavy, and breakable) and other fluorinated polymers, offering greater fire resistance, higher tensile modulus, and lower density than its direct competitors.

In addition to Halar® PV ECTFE, Solvay has launched new Halar® UV blocking technology which is the only solution of its kind in the industry. The new product 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 - Amcor Flexibles - 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.
