PEROXAN BEC

Polymerization of ethylene : PEROXAN BEC is used for high pressure in both autoclave and tubular processes, usually in combination with other peroxides of varying degrees of activity. Temperature range: 220 to 270°C Light-off temperature at 2300 bar: 220°C

Polymerization of styrene: PEROXAN BEC may be used in polymerization and copolymarization of styrene. In a mass process PEROXAN BEC can be used to increase polymerization rates. In suspension polymerization processes, PEROXAN BEC is often used for reduction of residual styrene content during the final polymerization stage. PEROXAN BEC is a benzene-free replacement of tert-Butyl peroxybenzoate (PEROXAN PB). Temperature range: 100 to 130°C Dosing: 0,02 to 0,1 phr

Polymerization of acrylates and methacrylates: PEROXAN BEC can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates. Temperature range: 90 to 130°C Dosing: 0,1 to 1 phr

• 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.
