STOCK SHAPE MACHINING AND PRODUCTION PROCESS THEREOF

摘要

A stock shape for machining, which is composed of an extruded product of a resin composition comprising 30 to 94% by mass of a thermoplastic resin (A), 5 to 40% by mass of a carbon precursor (B) having a volume resistivity of 102 to 1010 &OHgr;cm and 1 to 30% by mass of a conductive filler (C) having a volume resistivity lower than 102 &OHgr;·cm and has a thickness or diameter exceeding 3 mm, and a process for producing the stock shape by extrusion and solidification of the resin composition.
