Polymerization of ethylene:
PEROXAN DA is used for high pressure polymerization of ethylene in both autoclave and tubular processes, usually in combination with other peroxides of varying degrees of activity.
Temperature range: 240 to 280°C
Light-off temperature at 2300 bar: 265°C
Polymerization of styrene:
PEROXAN DA may be used in polymerization and copolymarization of styrene. In a mass process PEROXAN DA can be used to increase polymerization rates.
Temperature range: 95 to 185°C
Dosing: 0,02 to 0,1 phr
Polymerization of acrylates and methacrylates:
PEROXAN DA can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates.
Temperature range (solution polym.): 130 to 175°C
Dosing: 0,05 to 0,1 phr
Controlled rheology polypropylene (CR-PP) in an extrusion process:
PEROXAN DA allows great flexibility in controlling the melt flow index (MFI) of polypropylene. Small changes in either peroxide concentration or process temperature can produce significantly different MFIs. The MFI increases with the peroxide level.
Temperature range: 200 to 220°C
Dosing: 0,01 to 0,1 phr
PEROXAN DA is used for the curing of unsaturated polyester resins at elevated temperatures, in the temperature range from 120° to 160°C.
Furthermore, PEROXAN DA is used in polymerization of alkyde styrene resins.
Depending on working conditions, the following peroxide dosage level is recommended:
PEROXAN DA: 1,0 to 1,5 phr
