Clear Solar Eva Thin Film

We are providing of Solar EVA Thin Film.

Product definition

ZXEVA adhesive film applies to crystalline silicon and thin-film solar cells encapsulation, which is a kind of thin film, with Ethylene Vinyl Acetate co-polymer as the main raw material, adding variety of modified additives through sufficient mixing, heating and extrusion. The product is non-sticky and easy to operate at the room temperature. By heating, laminating and curing, it makes chemical reactions like cross-linking and bond enhancing to make the silicon wafers, glass and TPT becomes one firmly together as solar panel. The main function of this EVA film is to keep PV modules high light transmittance and high adhesion for long time, ensuring that the PV module can be used stably and efficiently for more than 25 years.
