Polycarbonate is a high-performance tough, amorphous and transparent thermoplastic polymer with organic functional groups linked together by carbonate groups (–O–(C=O)–O–) and offers a unique combination of properties. PC is popularly used as an engineering plastic owing to its unique features that include:

• High impact strength
• High dimensional stability
• Good electrical properties amongst others

Though the characteristics of polycarbonate are similar to polymethyl methacrylate (PMMA, acrylic), but polycarbonate is stronger, usable in a wider temperature range (Melting point: 155°C) but more expensive. As PC shows excellent compatibility with certain polymers, it is widely used in blends, such as PC/ABS, PC/ PET, PC/PMMA. Some of the common applications are compact disc, safety helmets, bullet-proof glass, car headlamp lenses, baby feeding bottles, roofing and glazing etc.
