Market Segments

Polymer production

Detailed description

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. Coagent for flame retardant polystyrene: Polystyrene is made flame retardant by the use of halogen-containing additives such as hexabromocyclododecane (HBCD). Perkadox® 14S-FL can be used as a synergist in such systems thereby leading to a significant reduction in the amount of HBCD required.

Polymer crosslinking

Detailed description

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.).
