PC Plastic Performance Introduction

  Polycarbonate (PC) plastic offers a combination of properties unmatched by general-purpose plastics, making it a premier engineering material. It is exceptionally suited for manufacturing small, precise components with complex geometries that must endure light loads or moderate impact. A key processing characteristic is that its melt viscosity decreases significantly with increased temperature, making it relatively easy to mold, though careful control is required to preserve its innate properties. The performance characteristics of PC are distinct: it possesses remarkably high impact resistance, even at low temperatures. It exhibits good heat resistance and maintains dimensional stability across a wide temperature range. Its optical properties are excellent, offering high transparency with light transmittance up to 90%. Furthermore, PC demonstrates low water absorption, good weatherability (especially when UV-stabilized), and is considered a non-toxic material. The broad application of PC across electronics, automotive, medical, and consumer goods hinges entirely on these performance attributes. Achieving optimal part quality, however, imposes strict requirements on the production process—from meticulous drying to precise control of melt temperature, injection speed, and mold temperature—to ensure the finished product retains the material's full suite of desirable characteristics.
