Take you to understand the raw material composition of the solar backsheet Source: Protective film factory direct sales Release time: 2019-05-17 Hits: 1595 Solar backsheet, also known as TPT material, consists of a 3-layer structure. The outer layer is a T film, and the middle layer is a P film. The T and P are glued together. Among them, T stands for polyvinyl fluoride film (PVF), with a thickness of about 37μm. This layer is the main layer used as a solar cell encapsulation material. Its function is weather resistance, UV resistance, aging resistance, and photosensitive resistance, etc.; P stands for PET film, The thickness is generally 250μm, the main function is water vapor barrier and electrical insulation, and it has the advantages of dimensional stability, easy processing and tear resistance. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 10 years of experience. It can produce PET film with various functions, such as: sub-(matte) PET film, flame-retardant (fireproof) 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!
