Fluon® ETFE Film

Fluoro polymer film for front sheet and back sheet of PV module

Applications

 

 

Fluoro polymer film for front sheet and back sheet of 
PV module 

 

The performance of Fluon® ETFE Film is highly valued by the construction and architectural  industry like football stadium in Munich, and the main stadium and the venue for aquatics events at the Summer Games in Beijing. And it is also widely used in the field of photovoltaics. 

White and black colored Fluon® ETFE Film is ideal for use as back sheets thanks to its durability and long service life. Transparent Fluon® ETFE Film is of course also used extensively in photovoltaics as front sheets for flexible modules or BIPV.
