    ISARD Encapsulation Film Series
    ISARD 2280 EVA film
    ISARD 2280 encapsulation film is produced by mixing ethylene-vinyl acetate copolymer resin (EVA) with various necessary additives. In a solar PV module, its purpose is to bind the glass and backsheet durably, and protect and fix solar cells. It has excellent electric insulation and strong resistance to dampness, heat and ultraviolet ageing. Its stable resistance to PID ensures that the module will work efficiently and durably outdoors.
