TPT flim
SP TPT is composed of high-performance fluorine resin and strong PET film(with UL standard)by special technology. We call the TPT as our FPF, which has acquired certificates from various international industrial associations such as TUV and SGS 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%. SP FPF have been well applied to hundreds of well-know enterprises in the world.
