ABSTRACT:
A conductive propylene resin composition, which is used for packaging and automatic feeding of parts which is unlikely be electrically charged, which is resistive to a baking treatment and which does not produce wastes and can reduce a material cost and a processing cost, is provided.The composition contains of(1) a % by weight of a propylene polymer with a portion having not less than 95% by weight of crystallinity that occupies not less than 60% by weight of the propylene polymer, and contains not more than 20% by weight of ethylene;(2) b % by weight of a propylene random copolymer which has a tensile elongation of not less than 100% and contains 1 to 7% by weight of ethylene; and(3) c % by weight of an electrically conductive filler, wherein the following relationships are satisfied: a+b+c=100, 0.5≦a/b≦2.0 and 10≦c≦30.
