We can rebuild the molecular weight of degraded recycled PP (polypropylene)
so that higher recycled content can be used in final products.
Most of the properties of recycled plastics are inferior
to those of virgin resin. Exposure to UV and sunlightduring the articles’ lifetime lead to degradation of thepolymer chains lowering their molecular weight. In
addition, recycled feedstocks with low MFI are scarce andexpensive.

Perkadox® PM-60ST-GR has shown extremely good
performance on recycled polypropylene (rPP) feedstocks
of different type: post-consumer/post-industrial rPP withdifferent starting MFI and different contamination levels(0 - 20% of other polymers, mainly HDPE).

Nouryon has patented a new technology in which
Perkadox® PM-60ST-GR is used in the extrusion step ofmechanical recycling to rebuild its molecular weight byadding long chain branches.
With the use of Perkadox® PM-60ST-GR the MFI of
recycled PP decreases. At the same time, the melt strengthand melt elasticity of the modified recycled PP increases
significantly, enabling new processing opportunities
and applications like foaming, blow molding and even
thermoforming.

Perkadox® 24L is used for decreasing the MFI of virgin
PP. Its use in the recycling industry is difficult due to its
relatively low decomposition temperature.

Boost the Mechanical Propertiesof your Recycled PP
Our innovative mechanical properties booster can lead to improved properties ofrecycled polypropylene: higher impact resistance, and greater tensile and flexuralstrength. As a result, this recycled PP can be used in higher end applications.
Perkadox® PM-60ST-GR generates long chain branches
on recycled polypropylene. The increased molecularweight of the modified recycled PP has a strong impact on
the performance of the polymer in terms of mechanicalproperties.

The graphs show improvement in mechanical properties

5A Wide Choice of Peroxides toIncrease the MFI of Recycled PP
Our proprietary products are a low odor solution to increase the MFI of
recycled polypropylene, obtaining a more homogeneous product quality forbetter processing at converters.
Recycled Polypropylene (PP) is produced from feedstocks
with different Melt Flow Indexes (MFI) resulting in varying
quality, causing instability during processing at converters.
In addition, recycled feedstocks are available in a restricted
MFI range, usually 10-20 gr/10 min, or 10-30.
Several peroxides such as Perkadox® 14, Trigonox® 101 andTrigonox® 501-CS40 are already used in the mechanicalrecycling of polypropylene to achieve a higher MFI,
enabling the use of recycled content in applications
requiring different properties than the available feedstocks.

Our latest generation peroxides for controlled-rheology,
Trigonox® 301 and Trigonox® 501-CS40, generate
lower VOC levels compared to traditional peroxides (i.e.
Trigonox® 101, Perkadox® 14). TBA and acetone as well
as aromatics are in fact absent when using Trigonox®
301 and Trigonox® 501-CS40. In addition, Trigonox® 301and Trigonox® 501-CS40 have FDA and BfR food contact
approvals. These peroxides have been widely adapted in
the virgin PP industry, and their low-odor characteristic
is making them the preferred choice in high end
applications.

Organic peroxides are also used to narrow the widemolecular weight distribution typical of recycled PP,
resulting in a constant and reproducible recycled PPquality. This helps avoiding undesirable fluctuations infurther processing steps.

temperature they tend to generate more gels than whenusing Trigonox® 301 and Trigonox® 501-CS40.
