ELECTROCONDUCTIVE RESIN COMPOSITE MATERIAL FOR MOLDING

摘要

: An electroconductive resin composite material for molding having excellent mechanical strength and electric properties. The resin comprises 100 parts by weight of polypropylene, from 10 to 50 parts by weight of a modified polypropylene obtained by either chemically modifying polypropylene with an organic unsaturated carboxylic acid or by copolymerizing propylene and the organic unsaturated carboxylic acid, from 5 to 65 parts by weight of carbon fiber having a diameter of 5 to 20 micrometers, the ratio of length to diameter of the fiber being not less than 10, and from 5 to 65 parts by weight of electroconductive carbon black, the specific surface area being at least 800 m2/g.
