Polymerization of styrene: PEROXAN PK295 V-75 may be used in bulk polymerization of styrene. Due to the bifunctionality of PEROXAN PK295 V-75 and the more constant reaction rate using this initiator, the resulting polymer has a higher molecular weight and shows reduced dispersity. Temperature range: 90 to 120°C Dosing: 0,02 to 0,1 phr
Polymerization of acrylates and methacrylates: PEROXAN PK295 V-75 can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates. Temperature range: 90 to 120°C Dosing: 0,05 to 1 phr
Other applications: PEROXAN PK295 V-75 may also be used for the (co)polymerization of acrylonitrile.

- Product Handling and Storage
- Maximum storage temperature (Ts max) : 30°C
- Storage stability as from date of delivery : 6 months
- Keep packaging tightly closed in a well ventilated place at indicated storage temperature. Keep away from reducing agents e.g. amines, acids, alkalis, heavy metal compounds (e.g. accelerators, driers, metal soaps). Never weigh out in storage room. Oxidizing agent. Decomposes violently under the influence of heat or by contact with reducing agent. Never mix with accelerators. 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.
