Abstract
A compounded plastic system containing 3 to 90% by weight of a crystalline polyolefine, 0.4 to 80% by weight of a non-crystalline polyolefine, 25 to 90% by weight of a pigment and/or filling agent, 0.5 to 10% by weight of surfactants, and optionally other polymers, wherein the system contains two surfactants of different HLB-values, the one surfactant having a HLB-value lower than 9 and the other surfactant having a HLB-value higher than 9, both surfactants being heat-resistant up to at least 160.degree. C. The compounded plastic system according to the invention retains the properties of the starting system even when admixed with widely varying amounts of filling agents, and even more, in certain respects it possesses improved characteristics.
