PCT No. PCT/JP83/00109 Sec. 371 Date Nov. 28, 1983 Sec. 102(e) Date Nov. 28, 1983 PCT Filed Apr. 11, 1983 PCT Pub. No. WO83/03610 PCT Pub. Date Oct. 27, 1983.An electro-conductive foam is prepared by mixing together 100 parts by weight of a resin component consisting of 10 to 90 parts by weight of a crystalline thermoplastic polyolefin type resin and 10 to 90 parts by weight of a low-crystalline thermoplastic resin with 5 to 40 parts by weight of electro-conductive carbon, by cross linking this mixture and then forming it by heating. By using the mixture of crystalline polyolefin type thermoplastic resins and low-crystalline thermoplastic resins as the resinous component, the present invention provides an electro-conductive foam having a good foam surface condition and capabilities of deep-draw forming. This electro-conductive foam is utilized as a material for semiconductor integrated circuit containers and similar applications.
