| Lushan® EVA adhesive film for solar cell can provide excellent optical properties and strong adhesion to glass, good aging resistance, long-time bonding stability, etc. Lushan® EN1050 film is mainly used to encapsulate solar cell and lamination glass in building and decoration industry. At normal temperature, it has no stickiness and is easy to deal. During thermal lamination, curing reaction leads to permanent adhesion strength. Lushan® EVA thermosetting film is also used to encapsulate small or micro solar cell components of the grass lamp, garden lamp, and building glass with replace of epoxy resin.
