Fiber Glass Reinforced Compounds Based on High Flow Polycarbonate Copolymers

摘要

Short fiber glass-filled LEXAN* resin High Flow Ductile (HFD) polycarbonate copolymer materials are characterized by significantly higher melt flow compared to their equivalent glass-filled standard polycarbonate samples. The glass-filled HFD compounds show 11-18°C lower HDT compared to the standard polycarbonate products, but have similar impact, mechanical, and dimensional stability properties. The glass-filled HFD materials allow for longer practical injection molding flow lengths and thinner wall parts. In addition, the glass-filled HFD copolymer samples show improved surface gloss in injection molded plaques. In general, increasing the resin melt temperature, mold temperature, and injection speeds during injection molding results in increasing surface gloss and improved aesthetic appearance. Due to their higher flow and lower HDT properties, the glass-filled HFD copolymer materials offer a broader injection molding process window to achieve a higher gloss surface.
