Polycarbonate is a highly durable thermoplastic with high impact-resistance and a wide range of applications. Like acrylic fiberglass, another thermoplastic, it can be formed into sheets. Unlike acrylic it is shatterproof. Polycarbonate is also more malleable than acrylic even at room temperatures. More resistant to extreme temperatures, it is ideal for cooler and hotter climates. It also has better light transmission than many types of glass. Once UV protected it can last for many years.
