Ethylene-vinyl acetate (EVA) sheets are environmentally friendly materials made from a copolymer of ethylene (E) and vinyl acetate (VA). They are a type of plastic that excels in flexibility, rubber elasticity, and low-temperature properties, maintaining flexibility down to -50°C. Additionally, they have excellent weather resistance and are highly resistant to stress cracking, water, and ultraviolet rays, making them outstanding materials. Our EVA products are used as films to bond and protect photovoltaic cells used in solar panels, adhering glass and back protective sheets (back sheets). Due to their strength against water and ultraviolet rays, they are ideal materials for adhesive encapsulation films used in solar panels outdoors.
