What is PC

Polycarbonate (PC) is a colorless, transparent, amorphous thermoplastic material. Due to its colorless transparency and excellent impact resistance, it is commonly used in applications such as CD/VCD discs, bottled water containers, baby bottles, resin lenses, bulletproof glass, car headlight covers, animal cages, luggage, the visors of astronauts' helmets for moon landings; and the outer casings of smartphones, among others.

Chemical and physical properties

Polycarbonate is a durable material. Although it has high impact-resistance, it has low scratch-resistance. Therefore, a hard coating is applied to polycarbonate eyewear lenses and polycarbonate exterior automotive components. The characteristics of polycarbonate compare to those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is stronger and will hold up longer to extreme temperature. Polycarbonate is highly transparent to visible light, with better light transmission than many kinds of glass.

Polycarbonate has a glass transition temperature of about 147 °C (297 °F; 420 K), so it softens gradually above this point and flows above about 155 °C (311 °F; 428 K).[8] Tools must be held at high temperatures, generally above 80 °C (176 °F; 353 K) to make strain-free and stress-free products. Low molecular mass grades are easier to mold than higher grades, but their strength is lower as a result. The toughest grades have the highest molecular mass, but are much more difficult to process.

Polycarbonate can undergo large plastic deformations without cracking or breaking. As a result, it can be processed and formed at room temperature using sheet metal techniques, such as bending on a brake. Even for sharp angle bends with a tight radius, heating may not be necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are needed, which cannot be made from sheet metal. PMMA/Acrylic, which is similar in appearance to polycarbonate, is brittle and cannot be bent at room temperature.
