Polycarbonate (PC) is a transparent, amorphous thermoplastic polymer known for its exceptional impact resistance and optical clarity, making it significantly tougher than acrylic or glass alternatives. It is widely used in applications demanding durability combined with transparency—including safety glazing, automotive windows, protective equipment, and consumer electronics—and is preferred where repeated impact, thermal cycling, or dimensional stability under load are critical concerns. Engineers select PC when standard brittle plastics fail, when weight savings over glass are essential, or when processing flexibility and design complexity justify slightly higher material costs.
