Polycarbonate sheets are thermoplastics made from plastic pellets mixed with substances that have properties that make the sheet flexible, yet expandable and retractable under heat and cold respectively, thereby making it more resistant to changes in weather conditions than other plastics due to its many outstanding properties. Strong, durable, transparent yet protective against UV rays, as well as being bendable, polycarbonate sheets are therefore widely used in making translucent walls and translucent roofs, etc.
