Abstract: The invention relates to an active ingredient composition which has a high content in thermosensitive foaming agents and one or more polyolefin resins, the portion which is larger in quantity being a metallocene and optionally the remaining resins being polar or nonpolar nonmetallocene polyolefin resins. All polyolefin resins add up to at least 10% by weight of the formulation and have a melting point between 80 and 170° C. The reduced dust active ingredient composition according to the invention is used for the masterbatch production of foamed plastics.

Abstract: A colorant composition comprising finely distributed colorants and a plurality of polyolefin waxes, wherein a metallocene polyolefin wax having a viscosity in the rant from 3000 to 80000 mPa·s and optionally further waxes, for example polar or nonpolar non-metallocene polyolefin waxes or homo- and/or copolymers of ethylene and/or propylene are present. All polyolefin waxes together make up at least 50% by weight of the formulation and melt in the temperature range between 50 and 170° C. The inventive colorant composition has reduced dusting and is used for the production of colored plastics parts.

Abstract: The invention relates to an active substance composition containing a high portion of one or more light-protecting products, such as multifunctional stabilizers, UV absorbers, nicker-quenchers and stabilizers on the basis of sterically hindered amines (HALS) and several polyolefin waxes, wherein one or more metallocene polyolefin waxes are used and optionally further waxes, for example polar or nonpolar non-metallocene polyolefin waxes are present. All polyolefin waxes together made up at least 10% by weight of the formulation and melt in the temperature range between 50 and 170° C. The inventive active substance composition has reduced dusting and is particularly used for the masterbatch production for producing stabilized and light-resistant plastic materials.

Abstract: Colorant composition finely divided colorants and two or more polyolefin waxes, the quantitatively greater fraction representing a metallocene wax, and the further waxes being polar or a polar non-metallocene-polyolefin waxes or copolymers of ethylene. All of the polyolefin waxes together make up at least 15% by weight of the formula, and melt between 70 and 15O0 C. The colorant composition of the invention features reduced dust and is used for masterbatch production.
