ETFE is a kind of fluorine-containing polymer thermoplastic material, the chemical name ethylene tetrafluoroethylene copolymer, in the 1970s, by the United States NASA and DuPont company jointly developed, and applied in the field of space. Because ETFE has strong light transmission and heat insulation, it is soon widely used in various fields.

Photovoltaic cell encapsulation film (EVA) is a thermosetting adhesive film that is used in the middle of laminated glass (EVA is the abbreviation of Ethylene Vinyl Vinyl Acetate Acetate). Due to the superiority of EVA film in adhesion, durability, optical properties, etc., it is more and more widely used in current components and various optical products. EVA film as a part of component for solal cells , it has many advantages. then how is EVA film produced? Below we will briefly introduce the production process of EVA film.Let's go it !
