TPT film for solar modules back sheet 1.Double-sided fluoride,double protection. 2.Composited with strong PET film.
TPT film for solar modules backsheet:
On the basis of PET complex film(PE structure PV back sheet), we use imported fluoride materials composite with PET film and developed TPT,TPE structure back sheet Successfully which is more anti-aging, more corrosion-resistant and higher barrier. The TPE structure back sheet is attractive in price and quality and has a high market competitiveness and market share.
