    Controlled rheology polypropylene: Trigonox 101-E32 is an efficient peroxide for the degradation of polypropylene (CR-PP) in the temperature range of 200-250°C. The diluted form of Trigonox 101-E32 in mineral oil 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. The white oil acts in PP also as a plasticizer to facilitate molding, e.g. for the fabrication of syringes for injectors.
