Polycarbonate Sheet - Material Information

Polycarbonate (PC) is a transparent, amorphous thermoplastic polymer known for its exceptional impact resistance, optical clarity, and dimensional stability. Combining high toughness with good thermal resistance, polycarbonate is widely used in safety glazing, optical components, electronic housings, and medical devices. It remains ductile even at sub-zero temperatures, offering a unique combination of strength and processability among engineering plastics.

Material Overview

Polycarbonate exhibits a glass transition temperature (Tg) around 147 °C and maintains excellent mechanical properties across a broad temperature range. Its amorphous structure allows for high transparency and optical uniformity. According to Wei et al. (2024), PC’s nonlinear viscoelastic behavior contributes to superior energy absorption under dynamic loading, ensuring high impact resistance and deformation recovery. Sabet (2023) demonstrated that incorporating 0.2 wt% graphene oxide increased tensile strength by 26% and improved the glass transition temperature by nearly 5 °C, enhancing both thermal and mechanical stability. Moreover, Gallucci and DeRudder (2009) reported that PC’s inherent flame retardancy, stiffness, and optical clarity make it indispensable for applications in optical lenses, CDs, bullet-resistant panels, and automotive glazing. Hybrid materials such as PC/ABS blends, as investigated by Krache and Debah (2011), exhibit improved toughness and impact strength—achieving up to 88 kJ/m²—while maintaining transparency and heat resistance.

Applications and Advantages

Due to its balance of transparency, toughness, and thermal stability, polycarbonate is used in glazing systems, safety shields, helmets, and precision optical components. In electronics, it is favored for durable casings, light fittings, and lenses. Medical-grade PC is employed for sterilizable equipment, while construction and aerospace sectors use it for transparent panels, visors, and cockpit canopies. Zeng et al. (2023) further demonstrated the sustainability of polycarbonate-based copolymers synthesized from CO?-derived monomers, achieving similar strength (?52 MPa) and 92% optical transmittance, opening paths for greener, high-performance materials. Polycarbonate’s resistance to shattering and its ability to maintain mechanical integrity under heat and stress continue to make it a cornerstone polymer in engineering and consumer applications alike.
