Without plastic additives, there are no plastics. Additives protect plastics from degradation during processing, facilitate their workability, stabilize them against thermal or UV-induced degradation during use, and expand the range of properties by modifying material characteristics. A unique combination of scientific depth, relevance, and practical application. The focus is primarily on additives for polyolefins, PVC, and engineering plastics. However, there is also detailed information on the stabilization of elastomers, rubbers, high-performance thermoplastics, and duroplasts. Unmatched: The only comprehensive work in the German language. This long-awaited fourth German edition of the historically successful classic has been completely revised and provides the latest information on all technical developments.
