2,5-Dimethyl-2,5-bis(tert-butylperoxy)hexane, 7.5% Polypropylene carrier
CAS Number: 78-63-7
Physical form: powder
Trigonox® 101-7.5PP is a peroxide formulation for the production of controlled rheology polypropylene (CR-PP).
Controlled Rheology Polypropylene: Trigonox® 101-7.5PP is a highly effective peroxide formulation for controlling the rheology of polypropylene (CR-PP) in the 200-250°C temperature range. This powdered masterbatch made from liquid Trigonox® 101-7.5PP allows for more accurate addition of peroxide to the polymer. A more uniform distribution of the peroxide throughout the polymer is also advantageous. The use of a powder formulation rather than a liquid form allows for better control of the viscosity reduction cracking process. Trigonox® 101-7.5PP gives polypropylene producers great flexibility in controlling the melt flow index (MFI) of the polymer. Small changes in peroxide concentration or process temperature can produce significantly different MFIs.
