The recycling of materials - post consumer as well as post industrial - is a great challenge for the plastic industry. Pressure from the legislation as well as consumers demand more and more drive the industry to increase their recycling rates. Often heterogeneous plastic waste as well as separated mono-fractions are not fit for the majority of applications. Scission and crosslinking of the polymer chains as well as incompatibility of different plastics account for their poor mechanical properties.

Blending these materials with a small amount of compatibilizer/modifier based on ethylene butyl acrylates and corresponding maleic anhydride grafted products results in a drastic increase of positive mechanical properties.

This approach turns plastic waste into valuable feedstock for various extrusion and moulding applications offering huge economic opportunities for plastic converters.
