TPE-34 is a new multi-layered back film based on one layer of excellent durability fluoropolymerfilm, one layer of high voltage insulation polyester film and one layer of high durability fluoropolyethyleneresin. The cell side treated with a special polyethylene layer which provides goodadhesion to EVA. The structure of "TPE-33" has been designed to provide the best performanceof properties in terms of moisture barrier, electrical insulation and weatherability.

Advantage of SFC PV Back Film
*Dimensional stability of backsheet makes vacuum lamination easier
*Less shrinkage both in machine and transverse direction of backsheet,avoids wrinkles during processing
*Depending on type of EVA the initial adhesion values can vary greatly
