For Crosslinking: Perkadox 14S-FL is a bifunctional peroxide which is used for the crosslinking of natural rubber and synthetic rubbers, as well as polyolefins. Rubber compounds containing Perkadox 14S-FL have excellent scorch safety, and under certain conditions one step mixing is possible. Safe processing temperature: 135°C (rheometer ts2 > 20 min.). Typical crosslinking temperature: 175°C (rheometer t90 about 12 min.).
For Polmer production: Controlled rheology polypropylene (CR-PP)
High melt-flow index polypropylene grades are produced by post reactor treatment. These high melt-flows are achieved by peroxide-initiated degradation during extrusion of the polypropylene. The advantage of this process is the high flexibility; the peroxide concentration controls the final viscosity. Perkadox 14S-FL is a very efficient initiator in this process. Perkadox 14S-FL also has very low volatility (its vapor pressure is 0.5 mm Hg at 50°C) and thus can be added by mixing into the hopper during extrusion.
Perkadox 14S-FL is an initiator for the production of controlled rheology polypropylene (CR-PP) in the temperature range 180-250°C allowing polypropylene producers great flexibility in controlling a polymer’s Melt Flow Index (MFI).
