Abstract
There is disclosed a polymer-based foam composition comprising a polymer and up to 20 M.-% particles of one or more inorganic particulate materials, based on the total weight of the composition, wherein the one or more inorganic particulate materials comprise less than 20 wt.-% Al, calculated as Al2O3-content. According to one aspect, the one or more inorganic particulate materials comprise phyllosilicates. Also part of the present invention is the use of such polymer-based foam compositions and their method of production.
