Polycarbonates (PC) are thermoplastic polymers known for their high impact resistance, transparency, and thermal stability. These properties make them ideal for automotive headlamp lenses, electronic devices like smartphones, and construction materials such as roofing sheets. In healthcare, they are used for medical devices due to their ability to withstand sterilization. The main advantages of polycarbonates include their strength, optical clarity, dimensional stability, and ease of molding, making them suitable for various demanding applications.
