EVA (Ethylene-Vinyl Acetate) glass interlayer is generally considered to be more resistant than PVB (Polyvinyl Butyral) glass interlayer in certain outdoor applications, particularly in terms of resistance to moisture and environmental stress.

While both PVB and EVA offer excellent UV resistance and can withstand prolonged exposure to sunlight without yellowing or deteriorating, studies have suggested that EVA may offer better resistance to moisture and environmental stress than PVB. This could potentially result in a longer lifespan and better performance in certain outdoor applications.
