<P>PROBLEM TO BE SOLVED: To provide a cover for a guide light, which, since it does not use a conventional flame retardant containing bromine or chlorine, has no fear of generating gas containing bromine or chlorine due to the flame retardant during burning, and that, is excellent for environment since it does not use any phosphorus-based flame retardant, and further, since it has flame resistant properties passing the UL94-5V test in a thin mold product without damaging various kinds of performance that polycarbonate resin has, is suitable for a cover for a guide light or the like requiring light-masking performance and high flame resistance properties, and has a high practical utility value. <P>SOLUTION: The cover for a guide light is made by molding polycarbonate resin (A), a silicone compound (B) with a main chain of a branch structure and an organic functional group made of an aromatic group or an aromatic group as well as a hydrocarbon group (excluding an aromatic group), a metal salt (C) of an aromatic sulfur compound, a metal salt (D) of perfluoroalkane sulfone acid, a fiber-forming type fluorine-containing polymer (E), and titanium dioxide (F). <P>COPYRIGHT: (C)2012,JPO&INPIT |
