Abstract
A heat resistant electrically conductive plastic sheet comprising (1) a base material layer A made of a base material resin composition comprising from 32 to 94 wt % of a polyphenylene ether resin (hereinafter referred to simply as PPE), from 4 to 61 wt % of a high-impact polystyrene resin (hereinafter referred to simply as HI) and from 2 to 17 wt % of a polyolefin resin and (2) an electrically conductive layer B made of an electrically conductive resin composition comprising from 10 to 85 wt % of PPE, from 8 to 82 wt % of HI and from 3 to 33 wt % of an electrical conductivity-imparting material, integrally laminated on one side or both sides of the base material layer A by coextrusion.
