Perkadox 30 is a flame-retardant synergist for polystyrene. CAS number: 1889-67-4 EINECS/ELINCS No.: 217-568-2 Applications: Synergist in fire-retardant polystyrene: Polystyrene, especially expandable polystyrene, is made fire-retardant by the use of halogen-containing additives such as hexa-bromocyclododecane (HBCD). Initiators such as Perkadox 30 are commonly used as synergistic co-agents to reduce the amount of HBCD required. Perkadox 30 is well suited to this application as it has sufficient thermal stability at the temperatures used in suspension polymerization. The addition of Perkadox 30 to styrene monomer immediately before the onset of polymerization will not affect the polymerization process. Polymerization of styrene: Perkadox 30 can also be used for the mass polymerization of styrene. Information provided by Nouryon |
