PV Backsheet (PS-330)

PV Backsheet PS-330 Back Film of SFC is manufactured to give a variety of designs from Thermoplastic and Fluor polymer, as a backing sheet for photovoltaic Solar Module due to its excellent strength, weather resistance, UV resistance and moisture barrier properties. PS-330, The "TPT" is a multi-layered back film based on two layers of excellent durability fluoropolymer PVF film and one layer of high voltage insulation polyester film. Excellent durability fluoropolymer PVF films also provides good adhesion to EVA. The structure of "PS-330" has been designed to provide the best performance of properties in terms of superior UV resistance, moisture barrier, electrical insulation and weatherability.
