Nouryon launches new technology for recycled polypropylene applications

This article was originally posted on Chemical Engineering Online.

Summary
Nouryon has introduced Perkadox PM-60ST-GR, an organic peroxide designed to restore performance in degraded recycled polypropylene (rPP). Touted as the first commercially available peroxide solution tailored for rPP, it aims to help recyclers, compounders, and processors improve material quality and expand application options for recycled PP.

What rPP property improvements (e.g., strength, consistency, processability) would most influence your decision to replace virgin PP with higher recycled content in your applications?

Nouryon (Amsterdam, the Netherlands) has introduced Perkadox PM-60ST-GR, a new organic peroxide technology for recycled polypropylene — one of the world’s most widely used plastics — that is designed to restore performance in degraded, recycled plastic material. The first commercially available organic peroxide solution of its kind, this solution enables plastic recyclers, compounders and processors […]

Curious if this lets us spec higher recycled PP in HVAC airstream parts (fan housings, drain pans) without creep or brittleness at 60 - 70°C. Any data on heat aging/creep and impact after multiple reprocess cycles, and effects on UL 2043/UL 94 and VOC/odor for airstream use?

Most peroxides visbreak PP to hit a target MFR, which helps flow but can kill impact; is PM-60ST-GR actually rebuilding MW/branching or just tightening MWD, and do you have Izod/elongation vs MFR data on post-consumer streams with 5 - 10% PE contamination? Also, how does it compare to Trigonox 101 on odor/VOC and yellowing at typical 200 - 400 ppm doses, and what’s the processing window/half-life at 190 - 230°C for stable dosing on a twin-screw?
