Polycarbonate Properties

Polycarbonate exhibits exceptional durability, boasting high impact-resistance while also offering lower scratch-resistance. To enhance its longevity, hard coatings are commonly applied to polycarbonate eyewear lenses and exterior automotive components. Compared to polymethyl methacrylate (PMMA or acrylic), polycarbonate is notably stronger and better suited to withstand extreme temperatures. When thermally processed, polycarbonate becomes fully amorphous, resulting in exceptional transparency to visible light, surpassing many glass varieties in light transmission.

With a glass transition temperature of approximately 147°C (297°F), polycarbonate gradually softens above this point and begins to flow beyond about 155°C (311°F). Maintaining tools at elevated temperatures, typically above 80°C (176°F), is crucial for producing strain-free and stress-free products. While lower molecular mass grades offer ease of molding, they sacrifice some strength. Conversely, the toughest polycarbonate grades possess higher molecular mass but present challenges in processing.


Electronics: Polycarbonate is widely used in electronic components due to its excellent electrical insulation and flame-retardant properties. It finds applications in power systems, telecommunications hardware, and high-stability capacitors.

Construction: In the construction industry, polycarbonate is utilized for domelights, glazing, roofing sheets, and sound walls. Its combination of durability and lightweight properties makes it a preferred choice for building materials.

3D Printing: Polycarbonate is extensively used in 3D printing, particularly for producing durable plastic products with a high melting point. Although challenging to handle, it offers strength and durability in professional-grade printing applications.

Data Storage: Polycarbonate plays a crucial role in data storage, especially in the production of compact discs, DVDs, and Blu-ray discs. Its injection-molding capabilities enable the creation of optical discs with precision and reliability.

Automotive, Aircraft, and Security Components: In automotive and aircraft industries, polycarbonate is favored for its smooth surfaces and high impact resistance, making it suitable for headlamp lenses, decorative bezels, and bulletproof glass. However, coatings are often applied to enhance scratch resistance. Additionally, it’s used in security components like theft-proof packaging.

Medical applications: 

Polycarbonate is extensively used in medical applications, meeting high standards like ISO 10993-1 and USP Class VI (PC-ISO). These grades offer excellent biocompatibility and can be sterilized using methods like steam, gamma radiation, or ethylene oxide. Trinseo maintains strict standards for its medical-grade plastics, ensuring safety and reliability. Moreover, advancements in aliphatic polycarbonates have improved biocompatibility and degradability, particularly beneficial for nanomedicine.
