A new line of high-performance PVDF (polyvinylidene fluoride) films specifically designed for photovoltaic front-sheet applications, is now commercially available. Rowlar™ has been developed by applying Rowland Technologies' advanced film design and manufacturing capabilities to bring the outstanding performance characteristics of Kynar ® PVDF to the photovoltaic front-sheet market. Used in architectural coatings for decades, Kynar® has demonstrated excellent weather resistance in punishing South Florida test conditions for over 40 years. Rowlar™ is the result of the proven performance of Kynar® PVDF combined with precision film engineering. Rowlar™ provides outstanding solar transmittance, outstanding UV resistance, superior abrasion resistance, excellent fire and chemical resistance, superior oxygen barrier, good moisture barrier, excellent adhesion to encapsulants.
Thin, flexible and lightweight, it offers a broad selection of standard gloss and low-glare surfaces. It is extremely transparent, has a lower refractive index than glass and allows modules to run cooler. Compared to ETFE film, it is more transparent, 50% more abrasion-resistant, and more cost effective.
Rowlar™ film is sold by Rowland under an agreement with Arkema and is available in a range of thicknesses, widths, and surface textures to meet virtually any design configuration and production requirement
