Overview
This peroxide formulation is supplied as white beads, developed for the production of controlled rheology polypropylene (CR-PP) in an extrusion process within the 200-250°C temperature range. It is a beads-form masterbatch of the liquid active ingredient, positioned as a new generation polymer modifier for controlled-rheology of both virgin and recycled polypropylene, and it is also used for decreasing the MFI of recycled polyethylene. This page summarizes the published specifications for this grade and outlines what buyers should consider before sourcing it.

Applications of Trigonox 301-20PP Across Market Segments
It is used by polypropylene producers to control a polymer’s Melt Flow Index (MFI) during extrusion. Small changes in either peroxide concentration or process temperature can produce significantly different MFIs, which gives converters a practical lever for tuning resin flow characteristics without changing the base polymer. Beyond virgin CR-PP, this grade is also applied to recycled polypropylene and for decreasing the MFI of recycled polyethylene, making it relevant to buyers working across both prime and recycled-content polymer streams.
Why the Beads Masterbatch Form of Trigonox 301-20PP Matters
This beads-form masterbatch allows more accurate dosage of the peroxide into the polymer stream compared with handling the liquid form directly. A more homogeneous distribution of the peroxide throughout the polymer is a further advantage of the beads format. Using it in beads form rather than as a neat liquid results in better control of the visbreaking process, which is a meaningful consideration for producers who need repeatable MFI targets batch after batch.
Why Sourcing Consistency Matters for Buyers
Because small shifts in peroxide concentration can produce significantly different MFI outcomes, lot-to-lot consistency in active oxygen content is a direct driver of process repeatability for polypropylene producers. A supplier that consistently delivers this grade within its stated 1.34-1.63% total active oxygen range and 421 kg/m³ bulk density reduces the need to re-tune dosage rates or extrusion parameters with every new batch.
This is particularly relevant for converters running continuous visbreaking lines, where an out-of-specification batch can shift MFI outside a customer’s accepted tolerance. Reviewing the certificate of analysis for active oxygen content and bulk density before a batch enters production is a reasonable quality check for this masterbatch grade.
What to Consider When Sourcing Trigonox 301-20PP
Buyers should confirm whether their line is processing virgin CR-PP, recycled polypropylene, or recycled polyethylene, since expected dosage and target MFI outcomes can differ across these streams even though the same masterbatch is used. Requesting the current safety data sheet alongside the certificate of analysis is a practical way to confirm that a given batch matches the appearance and active oxygen specifications listed above.
Extrusion temperature control within the 200-250°C processing range should also be reviewed against the buyer’s existing line setup, since process temperature interacts with peroxide concentration to determine final MFI. Packaging, storage requirements, and transport classification should be confirmed directly with the supplier given the regulatory requirements around organic peroxides.
General Handling and Storage Guidance
As with other organic peroxides, this product should be stored in accordance with the supplier’s safety data sheet, typically in a cool, dry, well-ventilated area away from direct sunlight, incompatible materials, and sources of heat or ignition. Personnel handling this masterbatch should follow the personal protective equipment and handling procedures specified in the SDS, since organic peroxides can decompose exothermically under certain storage or contamination conditions.
Buyers should request and review the current safety data sheet prior to receipt, and confirm that on-site storage conditions, including temperature control, are compatible with the recommended storage requirements for this grade. Proper inventory rotation and adherence to the stated shelf life help maintain the active oxygen content and MFI-control performance described above.
