ABSTRACT:
This invention provides an electrical conductive foam bead comprising a foamed bead core of a thermoplastic synthetic resin at least partially covered on the surface thereof with an electrical conductive layer, and a molded electrical conductive foamed article comprising a plurality of particulate bodies formed by mutually fusing such electrical conductive foam beads, the electrical conductive layers extending over all or a portion of the interface of the mutually fused particulate bodies. The conductive foam beads and molded conductive foamed articles both have improved antistatic effect and are used as packaging and cushioning materials, electromagnetic radiation shields, and the like.
