Popular science information about PC
PC (Polycarbonate) is a versatile and highly durable thermoplastic polymer that is widely used in various industries. It is formed through the polymerization of bisphenol A and phosgene.
One of the key advantages of PC is its exceptional impact resistance. It is known for its ability to withstand high levels of impact without breaking or shattering, making it an ideal choice for applications that require high strength and durability. PC is commonly used in safety equipment, automotive components, and electronic devices where impact resistance is crucial.
In addition to its impact resistance and transparency, PC is known for its high heat resistance. It has a high glass transition temperature, allowing it to withstand elevated temperatures without significant deformation or degradation. PC can typically withstand continuous use at temperatures up to 130°C (266°F) without losing its mechanical properties. This property makes it suitable for applications that require exposure to high temperatures, such as automotive components and electrical enclosures.
Another notable property of PC is its good chemical resistance. It is resistant to a wide range of chemicals, including acids, bases, and solvents. This property makes PC suitable for applications that require resistance to harsh chemicals, such as laboratory equipment and automotive components.
