TPT sheet for pv panel

*Width : 800mm ~ 1620mm
*Color : White(Other colors on request)
*Cut sheets according to customer's request
SS-320
, 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 "SS-320" has been designed to provide the best performance of properties
in terms of superior UV resistance, 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
