CONDUCTIVE COMPOSITE PLASTIC SHEET AND CONTAINER

摘要

PROBLEM TO BE SOLVED: To markedly reduce the falling-off of carbon black by the abrasion at a time of the contact with an IC by adding a mixture of an olefinic resin and two or more kinds of different block copolymers produced from styrene and conjugated diene to a conductive compsn. in a specific wt. ratio. SOLUTION: A sheet is produced by laminating a conductive compsn. consisting of a polystyrenic resin, carbon black, an olefinic resin and a styrene block copolymer to both surfaces of a sheet base material composed of a polyphenylene ether resin. The conductive compsn. contains 5-50 pts.wt. of carbon black per 100 pts.wt. of a thermoplastic resin and 1-30 pts.wt. of an olefinic resin and 0.2-10 pts.wt. of the styrene block copolymer are added to the sum total amt. of the thermoplastic resin and carbon black. In this conductive composite plastic sheet, the surface intrinsic resistance value of the sheet having the conductive compsn. laminated thereto is 10<2> -10<10>Ω.
