PURPOSE:To obtain a resin compsn. which gives a distributor cap excellent in mechanical properties at normal and high temps., electrical properties, resistance to nitric acid, weld characteristics, resistance to bleeding, and flame retardancy while preventing defects in product appearance and a lowering in productivity due to bleeding onto a metal mold in injection molding. CONSTITUTION:The compsn. comprises a crystalline propylene polymer resin, 3-15wt.% glass fiber, 5-20wt.% talc or mica, 3-20wt.% silica, 4-20wt.% modified polyolefin resin, 10-30wt.% halogenous flame retardant comprising ethylenebistetrabromophthalimide and/or decabromodiphenylethane, and 3-15wt.% auxiliary flame retardant. |
