• Storage stability from date of delivery: 6 months

Half-life data

• 10 hours/1 hour/1 minute (0.1 m/benzene): 41/57/90°C

appliance

• For (co-)polymerization reactions of styrene chlorides, either in bulk or in suspension.
• Temperature range: 45-60°C
• Recommended use: 0.03-0.15% (as supplied)
• Special advantages: less crusting in the reactor and fewer "fish eyes" in the polymer.
• It is recommended to use it in combination with a more thermally stable peroxide (e.g. Dilauroyl peroxide) to achieve a nearly constant rate of polymerization.

wrap

• Standard package: 20kg carton
