Initiator (20% masterbatch formulation on polypropylene beads) for the production of controlled rheology polypropylene (CR-PP). CAS number: 24748-23-0 EINECS/ELINCS No: 429-320-2 Applications: Trigonox 301-20PP is an efficient peroxide formulation for the production of controlled rheology polypropylene (CR-PP) in an extrusion process in the temperature range of 200-250°C. This beads form masterbatch of the liquid Trigonox 301- 20PP allows a more accurate dosage of the peroxide to the polymer. Also a more homogeneous distribution of the peroxide throughout the polymer is of advantage. Using the beads form formulation rather than the liquid form results in a better control of the visbreaking process. Trigonox 301-20PP allows polypropylene producers great flexibility in controlling a polymer’s Melt Flow Index (MFI). Small changes in either peroxide concentration or process temperature can produce significantly different MFI’s. Information provided by Nouryon |
