Abstract
PURPOSE: To provide the titled compsn. having excellent moldability, appearance of molded articles, mechanical properties and electrical conductivity, consisting of a propylene polymer, a high-density ethylene polymer, an inorg. filler and carbon black.
CONSTITUTION: 2W100pts.wt. carbon black having a specific surface area of 850m2/g or larger is blended with 100pts.wt. compsn. consisting of 80W25wt% propylene polymer having an MI of 0.01W30g/10min, 5W55wt% ethylene polymer having a density of 0.945g/cm3 or higher, and 15W70wt% inorg. filler having an average particle size of 100μ or smaller (e.g. TiO2 or glass bead).
EFFECT: The compsn. has excellent electromagnetic wave-shielding properties, rigidity and dimensional accuracy, and is suitable for use in business machines and electronic equipments which have to avoid electromagnetic wave interference.
