| 摘要 |
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. |
