Introduction of Recycled Crosslinked Materials into New Parts

Crosslinked polyethylene is a major problem for the rotational molding industry as very limited information is available on its recyclability and waste management. In this presentation, some preliminary results will be presented on the possibilities to process/recycle crosslinked polyethylene with respect to materials and methods. Then, a study on the reintroduction of the recycled materials into virgin resins will be discussed in terms of concentration and processing conditions. Finally, general conclusions will be made with proposal for future development on similar as well as other applications. As a fist step, only single layers of the same resin is used to better understand the relationships and interactions between the processing conditions and the final parts properties.
