Details Of TPT/TPE Backsheet
Specifications Of TPT/TPE Backsheet
BEC301 is a multi-layer structure Backsheet. The middle PET layer provides mechanical strength and electric insulation; and the inner and outer lays of fluorine resin ensure the excellent durability for this Backsheet and could protect the solar cell endure high temperature through the lamination process. The high light-reflectivity of the inner side of fluorine resin also can help to increase solar module’s efficiency.There are white and black colors of BEC-301
