| Abstract |
Starting from the growing importance of polymer recycling, and the dominant role of polyolefins as materials with low carbon footprint and wide application range, the issues of mechanical recycling of polyethylenes and polypropylenes are discussed. Limited compatibility creates challenges when "Closing the loop", but Borealis and its partners in the circular economy field are developing advanced recycling technologies, for which not only improved sorting and quality control, but also the use of advanced copolymers for improving compatibility, processabilty and mechanics is being studied. The application of multi-phase impact copolymers is shown to be especially efficient, while also being much more economical than special compatibilizers or impact modifiers, which also tend to excessively reduce the modulus of the resulting compositions. A thorough understanding of the structure-property relations underlying the upgrading process is clearly required, and a wide range of applications - from advance packaging to automotive - can be covered consequently. |
