Polycarbonate is an amorphous thermoplastic material, boasting excellent heat resistance, good transparency, and very high impact strength, among its physical and mechanical properties.PC is a non-crystalline engineering material with exceptional impact strength, thermal stability, luster, antibacterial properties, flame retardancy, and resistance to contamination. The PC's notched Izod impact strength is very high, and its shrinkage rate is low, typically ranging from 0.1% to 0.2%. PC boasts excellent mechanical properties, but poor flow characteristics, making injection molding with this material more challenging.Used for manufacturing various gears, racks, worm gears, worm shafts, bearings, cams, bolts, levers, crankshafts, ratchets, and also serves as parts for some mechanical equipment, such as casings, covers, and frames.Cups, tubes, bottles for medical use, dental instruments, pharmaceutical containers, surgical instruments, and even artificial organs like artificial kidneys and lungs.
