ETFE is highly transparent ,weather resistance, anti adhesive ,it can be used for front and back sheet protection of photovaltaic modules .ETFE film for photovoltaic modules provides a strong dirt repellent effect to the outside.It allows a strong connection to the encapsulation film on the inside.
ETFE film is a fluoropolymer film and ETFE film is developed specifically as a convection barrier for solar collectors, as well as for photovoltaic modules surface protection.
ETFE film is also used effectively to substitute glass in the front sheet area and thus significantly reduce the weight of modules.
Very good mechanical strength High weather resistance High light transmission also in the UV range Low basis weight Self-cleaning effect due to anti-adhesive surface Excellent adhesive properties to the EVA encapsulation film
