Polymerization of ethylene : PEROXAN PK234 W is used for high pressure in both autoclave and tubular processes, usually in combination with other peroxides of varying degrees of activity. Temperature range: 190 to 250°C Light-off temperature at 2300 bar: 219°C
Polymerization of styrene: PEROXAN PK234 W may be used in polymerization and copolymarization of styrene. In a mass process PEROXAN PK234 W can be used to increase polymerization rates. In suspension polymerization processes, PEROXAN PK234 W is often used for reduction of residual styrene content during the final polymerization stage. Temperature range: 90 to 130°C Dosing: 0,02 to 0,1 phr
Polymerization of acrylates and methacrylates: PEROXAN PK234 W can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates. Temperature range: 100 to 140°C Dosing: 0,1 to 1 phr
Other applications: PEROXAN PK234 W may also be used for the (co)polymerization of acrylonitrile and divinylbenzene.

- Organic Peroxides are more or less stable products but will decompose under the influence of heat. To minimize a loss of quality during storage, it is important that the recommended maximum storage temperature is not exceeded. If a minimum storage temperature is given, an undesirable process such as a solidification or phase separation, is known to occur below this temperature.
- Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN PK234 W.
