Polycarbonate (PC) is an amorphous thermoplastic resin with excellent comprehensive properties. It has excellent electrical insulation, elongation, dimensional stability and chemical resistance, as well as high strength, heat resistance and cold resistance. It used in engineering are stronger, tough materials, and some grades are optically transparent.

Features and applications


Polycarbonate has a glass transition temperature of about 147 °C (297 °F),so it softens gradually above this point and flows above about 155 °C (311 °F).Tools must be held at high temperatures, generally above 80 °C (176 °F) 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 more difficult to process.

Unlike most thermoplastics, 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.
