Reactive recycling technology for the circular use of plastics
Nexam Chemical supply reactive additives in masterbatches (IV enhancers, MFR modifiers) that upcycle, modify and solve recycled polymer processing/property challenges for rPET, rPE and rPP.
‘Reactive Recycling’ technology is largely patented, and claimed to rebuild and restore material properties of used plastics processed in recycling centres. This claim has been scientifically verified by a team of scientists at the Politecnico di Torino, in a study published earlier this year. The technology enables plastics to return to full circulation and continued reuse. A masterbatch of active ingredients is added to the extruder of recycled feedstock. Upon reaching the activation temperature, the feedstock is chemically modified and regains properties lost during the conventional recycling process. The masterbatch is fully reacted and incorporated into the plastics.
Reactive recycling rebuilds polymer chains, increasing melt strength and viscosity, thereby enabling recycled feedstocks to be used in more advanced end product applications. Processing is also more consistent and mechanical properties improved, says the company.
The technology is claimed to be approved for food contact and suitable to all rPET applications, e.g. bottles, sheets, films etc.
