Polycarbonate is a group of thermoplastic polymers that contain carbonate groups in their chemical structures. They are strong, tough materials that are easily worked, molded, and thermoformed, making them valuable in prototyping applications where transparent or electrically non-conductive parts are needed. Polycarbonate is also used in engineering applications where robust materials are required, such as in impact-resistant "glass-like" surfaces. Some key characteristics of polycarbonate include:
-
Durability: Polycarbonate is virtually unbreakable and highly impact and shatter-resistant.
-
Transparency: Polycarbonate is a naturally transparent amorphous thermoplastic that can internally transmit light almost as effectively as glass.
-
Ease of processing: Unlike most thermoplastics, polycarbonate can undergo large plastic deformations without cracking or breaking, and can be processed and formed at room temperature using sheet metal techniques.
Polycarbonate is used in a wide range of applications, including eyeglasses, medical devices, auto parts, 3D printed models for high heat applications, machinery guards, LED light pipes and diffusers, vehicle headlights, small vehicle windshields, bullet-resistant "glass," phone and computer cases, fountain pens, and luggage. It is also a popular material for prototypes due to its durability and transparency. Polycarbonate is considerably less toxic than many other plastics, and it can be recycled easily, making it an environmentally friendly choice.
