ABSTRACT:
Highly loaded improved closed cell foams comprising a plurality of coalesced strands or profiles of an alkenyl aromatic thermoplastic synthetic resin or mixture of an olefin polymer resin and a copolymer of ethylene with one or more copolymerizable comonomers having a lower melting point than the olefin polymer resin. The loading of the nucleating additive is in a range of about 0.5 to about 50 weight percent, based on total resin weight. When highly loaded with carbon black these foams are electroconductive foams.
