Trigonox 101-7.5PP is a peroxide formulation for the production of controlled rheology polypropylene (CRPP). CAS number: 78-63-7 EINECS/ELINCS No: 201-128-1 Applications: Controlled rheology polypropylene: Trigonox 101-7.5PP is an efficient peroxide formulation for the controlled rheology of polypropylene (CR-PP) in the temperature range of 200-250°C. This powder form masterbatch of the liquid Trigonox 101-7.5PP 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 powder form formulation rather than the liquid form results in a better control of the visbreaking process. Trigonox 101-7.5PP 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 |
