PURPOSE:To obtain an excellent sound shielding property and a good adhesive property and good molding appearance by mixing denatured polyolefin, metallic powder and a fiber inorganic filler at a preset ratio into a resin mixture of polypropylene and polyamide at a specific ratio. CONSTITUTION:Denatured polyolefin, metallic powder and a fiber inorganic filler are mixed at a preset ratio into a resin mixture of polypropyle and polyamide. A resin mixture 10-20wt.% containing polypropylene and polyamide at the ratio 10:90-70:30wt.%, denatured polyolefin 0.5-5wt.%, metallic powder 65-85wt.%, and a fiber inorganic filler 3-10wt.% are contained, and the density is 2.5g/cm or above. The sound shielding property and the adhesive property to an epoxy sealing agent are excellent, and molding appearance is improved. |
