DuPont Says Entira~(TM) EP Copolymers Help to Enable Mixed-plastic Recycling

摘要

DuPont says its new series of Entira~(TM) EP technology and copolymers are able to boost the performance of recycled polyolefins to a similar level as virgin resins, thereby improving the prospects for recycling mixed-plastics waste streams. Mixed waste streams containing polypropylene (PP) and polyethylene (PE) can be difficult to separate due to the similarities in densities. If one of these polymers contaminates the waste stream of the other, it tends to yield materials with very low mechanical properties. This can make it difficult or impossible to process such feedstock using standard polymer extrusion or injection technologies.
