PV-Rück für Solarzelle Verkapselung

PV backsheet for solar cell encapsulation 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.
