PVF /PVDF and other fluorine film + PET film + PVF /PVDF and other fluorine film 3 layer composite process, that is, the solar backplane consists of 3 layers Structural composition, the outer layer is a T film, the middle layer is a P film, and the T and P are glued together. Among them, T represents polyvinyl fluoride (PVF)/polyvinylidene fluoride (PVDF) and other fluorine-containing films. This layer is used as the main layer of solar cell encapsulation materials, and its function is weather resistance, UV resistance, aging resistance, etc.; P Said polyester film (BOPET), the main function is electrical insulation and water vapor barrier, and has the advantages of heat and humidity resistance, dimensional stability, tear resistance and easy processing. 2. The ordinary PET film is used as the base material of the intermediate layer, and the modified polyester film is laminated on both sides, namely: a three-layer composite process of modified polyester film + ordinary polyester film + modified polyester film. Among them, the role of modified polyester film material is equivalent to fluorine-containing film. 3. The PET film is used as the base material, and the fluorine-containing resin is coated and cured on the surface of the PET film by the surface coating process. Foshan Bowei Environmental Protection Material Co., Ltd. is a supplier of electronic materials with 10 experiences. It can produce PET film with multiple functions, such as: sub-(matte) PET film, flame-retardant (fire-resistant) PET film, inkjet printing film , Anti-static PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, etc. Interested parties welcome to inquire!
