  • Electro-conductive thermoplastic resin foam and preparation process thereof
    Patent number: 4525297
    Abstract: 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.
