Lamp reflecting mirror comprising polyphenylene sulfide, calcium silicate whiskers and a granular inorganic filler |
摘要 |
The invention provides a lamp reflecting mirror in which sufficient light reflecting characteristic (surface smoothness) can be obtained without application of any undercoat layer and in which heat resisting property, luminous intensity distributing performance (dimensional stability) and form retaining characteristic (material stiffness) at the time of adjustment of the optical axis can be satisfied at the same time. The lamp reflecting mirror is produced by injection molding a composition containing 30 to 50% by weight of polyphenylene sulfide resin, 5 to 30% by weight of calcium silicate whiskers, and 20 to 65% by weight of granular inorganic filler.
