METHOD FOR INCREASING THE CONCENTRATION OF AT LEAST ONE POLYMER FROM A POLYMER-CONTAINING WASTE MATERIAL, AND POLYMER RECYCLATE

摘要

The invention relates to a solvent-based plastics-recycling method which can reclaim polymers from polymer-containing plastics waste materials. The method is based on the use of a solvent which has been doped with heat stabilizer and which takes the form of solid-liquid extraction process to extract polymers at temperatures above 70°C from the plastics waste material. The method proposed can provide polymer recyclates which have improved mechanical properties in comparison with conventional recycled polymers. The use of at least one heat stabilizer in at least one organic solvent is also proposed for the solvent-based isolation of at least one polymer from a polymer-containing waste material.
