    摘要： The present invention is directed to a coaxial cable comprising (a) an inner conductor, (b) an outer conductor, and (c) a foamed insulation, surrounding the inner conductor. The foamed insulation is prepared from an insulation composition comprising a foamable polymer, a foaming agent, and a particulate, non-halogenated, nonheterocyclic polyolefinic nucleating agent. The invention is also related to methods and compositions for making the foamed insulation.

    摘要： An extruded polymeric foam comprising a styrenic polymer and an olefinic polymer, the olefinic polymer in an amount less than the amount of the styrenic polymer. The styrenic polymer and the olefinic polymer are present as a blend, preferably free of an interpolymer or compatiblizer. The foam has a density below about 36 kg/m3 (as measured by ASTM D1622-03), a vertical compressive strength greater than about 100 kPa (as measured by ASTM D1621-04) and a compressive strength ratio greater than about 0.35.
