Foamable electroconductive polyolefin resin compositions

摘要

A foamable, electroconductive polyolefinic resin composition comprising 70 to 95 weight percent of a polyolefinic resin and 5 to 30 weight percent of an electrically-conductive particulate furnace black having a specific surface area of at least 900 square meters per gram. Foam products prepared from this composition, preferably by extrusion foaming, are particularly useful for packaging sensitive electronic parts.
