▎ 摘  要

NOVELTY - Composition comprises a base polymer (12), talc (14) blended with the base polymer, and a citrate compound (16) blended with the base polymer. USE - The composition is useful: for fabricating a foamed article (claimed) which is used in a wide range of cables components e.g. insulation, separator or tape and jacket as an insulator, a separator and a jacket for cables e.g. communications cable. ADVANTAGE - The composition: provides enhanced small and closed cell foaming for multiple aspects of the cable design; provides shielding of electromagnetic radiation; provides a dual functionality and can be finely tuned as to a materials conductivity; reduces cross talk at a given frequency, thus enabling high performance cable properties; and achieves shielding effectiveness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for fabricating a foamed article comprising heating the composition to a temperature sufficient to cause decomposition of talc to generate a gas for foaming the composition. DESCRIPTION OF DRAWING(S) - The figure shows a foamable pellets. 10Pellets 12Base polymer 14Talc 16Citrate compound
