Solid white polyolefin sheets with a matte/matte finish. As an alternative to polystyrene sheets, polypro is extremely impact resistant and can be used for both indoor and outdoor applications. Polypro's moisture resistance, cracking-resistance, and UV stability make it an ideal choice for an outdoor application that offers an option for recycling at end of life.
