Material Notes:
EVA film for encapsulating solar modules Lushan EV1050G1 is mainly used for PV module encapsulation. It’s based on an ethylene vinyle acetate (EVA) copolymer and supplemented by special Chemical Accessories. EVA film for encapsulating solar modules Lushan series could effectively protect to the PV cell, and has excellent performance of transmittance and ageing-resistant. It provides structural support, electrical isolation, physical isolation/protection, and thermal conduction for solar circuits, as well as to maximize the service life of solar module. Solar EVA Film Characteristic:High volume resistivity and lasting adhesion strength holding capacity, and insure PV modules have long service lifeLow yellowness index change and low light transmittance attenuation, insure the high service efficiency of PV modulesExcellent compatibility with flux, welding ribbon, location tap, backsheet and silica gelSolar EVA film quality stability ensured by the complete and scientific quality management system.Information provided by Lushan
