NOVELTY - A polycarbonate composition comprises 50-90 pts. wt. polycarbonate, 6-10 pts. wt. glass fiber, 8-20 pts. wt. modifier, 15-20 pts. wt. flame retardant, 0.75-1.5 pts. wt. antioxidant, and 6-8 pts. wt. toughening agent. USE - Polycarbonate composition. ADVANTAGE - The composition comprises glass fiber, which has excellent mechanical strength, has improved processing fluidity, and excellent flame retardance, heat resistance and low temperature impact resistance, and improves the problems of easy stress cracking caused by internal stress, sensitive gap and poor solvent resistance. The glass fiber is mixed with other substances, and does not affect the mechanical performance of the composition. The composition is uniformly distributed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the polycarbonate composition, which involves: drying polycarbonate and modifier, mixing, and evenly stirring to obtain mixture (A); evenly mixing and stirring flame retardant, antioxidant and toughening agent, adding to mixture (A), continuously adding glass fiber, mixing, and stirring to obtain mixture (B); and extruding mixture (B), cooling, and granulating.
