摘要:
Disclosed are a thermoplastic resin composition for a light reflector which composition contains 2 to 45 parts by mass of an inorganic filler (B1) treated with a fatty acid type surface treating agent and havng an average particle diameter of not more than 3 μm, per 100 parts by mass of a thermoplastic resin (A); a thermoplastic resin composition for a light reflector which composition contains 2 to 45 parts by mass of an inorganic filler (B2) having a refractive index a of 1.61≦α≦2.5 and having an average particle diameter of not more than 3 μm, per 100 parts by mass of a thermoplastic resin (A); a thermoplastic resin composition for a light reflector which composition contains both 0.01 to 3 parts by mass of glycerol triester of a fatty acid and/or a glycerol diester of a fatty acid (C1), and 0.01 to 3 parts by mass of a glycerol monoester of a fatty acid (C2), per 100 parts by mass of a thermoplastic resin (A); a molded article for a light reflector which molded article is produced from one of such thermoplastic resin compositions as described above; and a light reflector in which a light reflecting metal layer is directly formed on at least a part of the surface of the molded article for a light reflector.
摘要:
Disclosed are a thermoplastic resin composition which has a reduced tendency to mold staining while being shaped and a high flowability, and a shaped article which, when used as a lamp component, has good surface appearance and generates little volatiles by the heat of the lamp. Specifically disclosed are a thermoplastic resin composition containing a polyester resin (A), a cresol novolac epoxy resin (B), and a vinyl cyanide-aromatic vinyl copolymer containing epoxy group (C), and a shaped article shaped therefrom, wherein the cresol novolac epoxy resin (B) and the vinyl cyanide-aromatic vinyl copolymer containing epoxy group (C) are compounded in amounts of 0.01 to 3 parts by mass and 2 to 12 parts by mass, respectively, relative to 100 parts by mass of the polyester resin (A).
