[0002] As we all know, polycarbonate is a tough thermoplastic resin. Polycarbonate processing is a general term for various processes that convert polycarbonate into resin products. Due to the particularity of polycarbonate structure, it has become the fastest growing general engineering plastic among the five major engineering plastics. During processing, in order to facilitate packaging, storage and transportation, a pelletizing device is usually installed at the tail of the polycarbonate extruder.
