PCT No. PCT/JP95/00218 Sec. 371 Date Aug. 13, 1997 Sec. 102(e) Date Aug. 13, 1997 PCT Filed Feb. 16, 1995 PCT Pub. No. WO96/25460 PCT Pub. Date Aug. 22, 1996The invention relates to crystalline polyolefin resin compositions obtained by blending 40 to 85% by weight of a crystalline propylene polymer, 3 to 40% by weight of an inorganic filler, 7 to 30% by weight of a halogen-containing flame retardant comprising ethylenebistetrabromophthalimide, decabromodiphenylethane, or their mixture, and 3 to 15% by weight of a flame retarding auxiliary; and electrical insulating parts obtained by molding the crystalline polyolefin resin composition. By using the crystalline polyolefin resin compositions of the invention, blooming (separation, in a powder-like form, of an ingredient) on the surface of a mold at the time of injection molding can be prevented, deterioration in appearance of final products due to the transfer of the bleeded ingredient to the surface of the mold is obviated, and decrease in productivity caused by wiping the bleeded ingredient off the mold can be avoided. In addition to the bleeding property onto the mold, mechanical properties (tensile strength and bending elastic modulus), electrical property, bleeding property of final products, appearance of final products, and flame retardancy can be satisfied at the same time by using the composition. Therefore, the crystalline polyolefin resin compositions of the present invention can widely be used for electrical insulating parts including deflection yoke separators.
