Rebuilding the Properties of Recycled Polyolefins
Bridging the gap between virgin and recycled Polypropylene (PP) and Polyethylene (PE)
The issues being debated daily in the recycling industry are many. While brand owners are committing to bold recycled content claims and legislations are being developed to push for recycling and establish governance, problems such as quality and availability of recyclate could hinder the development of this industry.
We identified 3 main issues:
We provide solutions for all three issues, bringing to the recycling industry not only improved quality and availability of recyclate but also higher flexibility and more opportunities. In fact, our products enable recyclers to produce many polypropylene grades from available waste streams. Moreover they give recyclers and compounders the possibility to expand the range of applications.
Our products are used at the end of the Mechanical Recycling process, during the extrusion step. Activated by temperature, they decompose to generate reactive radicals that modify the recyclate. Only traces of their presence are left in the final recyclate, at levels of only parts per million, (ppm level) allowing 100% recycled content claims.
One of the solutions we have developed to address these challenges is Perkadox® PM-60ST-GR, a polymer modifier designed to unlock more value from recycled polypropylene (rPP). By decreasing the melt flow index (MFI) of rPP while simultaneously improving melt strength and mechanical properties, Perkadox® PM-60ST-GR enables recyclers and compounders to overcome common performance limitations of post-consumer recycled material.
This makes it possible to broaden the MFI window, work with a wider range of recycled feedstocks, and target more demanding applications that were previously difficult to reach with rPP. As a result, rPP can move closer to virgin-like performance—without compromising recycled content ambitions.
