Polycarbonate Sheet Suppliers in UAE Polycarbonate (PC) is a thermoplastic that contains carbonate in its chemical structure. It is a strong and tough material and has a high impact resistance. It is produced by the reaction of Bisphenol A with phosgene.
PC is used in the data storage industry, electronic industry, construction material, 3D printing, security components and more. Since PC is scratch resistant it is hard coated when used to make eyewear lenses and automotive components. It is mainly used in applications that require low weight and high impact resistance. Polycarbonate can be easily fabricated and various fabrication processes are cutting, bending, milling, sanding, polishing, bonding and finishing. Sometimes it is required to bend the polycarbonate sheet to get the desired shape. The different bending techniques that are used are cold line bend and hot line bend. The difference between them is that one is carried out at a higher temperature than the other. To get accurate bends computer-controlled machines are used. A wide range of bending operations can be carried out using the machine and it has become a popular method. When polycarbonate sheets are bent the surface of the sheet is subjected to two forces: compressive and stretching force. The inner surface is subjected to compressive force and the outer surface is subjected to a stretching force. These forces should be controlled otherwise the sheet will crack or fracture. There are different types of polycarbonate sheets provided by polycarbonate sheet suppliers in UAE. They are crystal polycarbonate sheets, multi-wall polycarbonate sheets, tinted solid polycarbonate sheets and fire-resistant polycarbonate sheets. Bending techniques Cold line bend In this method, heat is not required. The bending radius depends on the thickness of the PC sheet. The PC sheet is clamped and slight force is applied to bend the sheet. The bending force should exceed the recommended values. Sharp tools should not be used to bend as they may damage the sheet. You should not force the sheet to conform to a specific shape. When bending textured PC sheets the textured surface should be inside. This is an efficient bending process and ensures low costs. Hot line bend This method is used to bend thick sheets and when an acute angle is required. Heat is required for the process. The PC sheet is heated along the line of bend either on one side or both sides. To heat the sheet the bending machine uses an electric heater. The machine has a temperature-controlled heater so there is no need to manually switch on and off. Once the sheet is heated pressure is applied to bend the sheet. You should apply pressure carefully depending on the thickness of the sheet. You can bend the sheet to conform to the outer surface of any shape.
