characteristics of Dicumene

Dicumene has unique structure and distinctive performance characteristics. By virtue of these, it can have a variety of functions, one of which is the flame retardancy in polyethylene.

Because of the particularity of the structure, the C-C bond between the corresponding quaternary carbon atoms is not stable, and it is easy to dissociate and form the free radical. So dicumene can be used as a free radical initiator for unstable C-C bonds, which are mainly used as flame retardants and Crosslinking Copolymerization catalysts.

Compared with the general free radical initiator, such as peroxide and azo compound, it is obvious that dicumene is more stable and safe to use. When dicumene is used as a synergist of flame retardancy, the halogen chain can be transferred by generating free radicals. And when the external temperature rises, it can promote to generate the halogen free radical to achieve the effect of flame retardance.
