The efficiency of the nucleation of talc in the procedure of foaming and foam cell structure of polymer based

摘要

Abstract invention patent: "efficiency of the nucleation of talc in the procedure of foaming and foam cell structure of polymer based". The present invention relates to a composition of polymer based foam comprising a polymer; and up to 20% by weight of particles of talc, based on the total weight of the composition. The particles of talc are microcrystalline powder.
