PTEROFLAT XT Solid PC Sheets are unbreakable Polycarbonate transparent sheets. Thanks to their outstanding toughness and heat resistance, they are the perfect solution for any outdoor usage with extra strength and durability needs. They are highly stable under outdoor weather conditions. Relying on UV radiation persistence, they do not show any substantial variations in their properties even after years of exposure to sunlight. The protective film must be removed immediately after an outdoor application in order to avoid the risk of permanent adhesion of the film caused by sunlight.
