TPT backsheet:

LIPUTER TPT is composed of high-performance fluorine resin(we get it from AGC in Japan) and strong PET film(with UL standard)by special technology. We call the TPT as our LIPUTER FPF, which has acquired certificates from various international industrial associations such as TUV and ROHS for it has completely met the demands of solar module components standard. In the experiments of weather resistance--irradiated by 2.5million LY(equal to 25years' use), our FPF can keep shiny at more than 80%. liputer FPF have been well applied to hundreds of well-know enterprises in the world.
