Nouryon has introduced Perkadox PM-60ST-GR, a new organic peroxide technology for recycled polypropylene, one of the world’s most widely used plastics. 

Perkadox PM-60ST-GR is designed to restore performance in degraded, recycled plastic material. This is the first commercially available organic peroxide solution of its kind. 

This solution enables plastic recyclers, compounders, and processors to use more recycled material in packaging, automotive, and consumer goods applications that have traditionally required virgin polypropylene.

Added during the extrusion step in polymer recycling, Perkadox rebuilds the polymer’s molecular structure, restoring the strength and consistency manufacturers need.

In testing, the product increased the plastic’s resistance to deformation when molten by up to 10 times and increased the melt viscosity. This gave processors more control over the recycled material’s behavior during processing.

“Recycled plastic has enormous potential but performance limitations have kept it out of many applications where it could make the biggest difference,” said Alain Rynwalt, senior vice president for Performance Materials at Nouryon. “Perkadox changes what’s possible. For the first time, recyclers and processors have a practical tool to restore the performance of recycled polypropylene and get it into packaging, automotive and consumer goods that the industry has traditionally assumed needed unprocessed plastic. That’s a significant step forward for our customers.”

Nouryon is presenting Perkadox PM-60ST-GR at the Plastics Recycling Show Europe (PRSE) 2026 in Amsterdam from May 5-6, 2026.
