Highly loaded coalesced foam

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