United Initiators Inc. has developed additives that improve flame retardance in new generation flame retardants replacing hexabromocyclododecane and similar bromine chemicals in expandable polystyrene and polystyrene foam.
Curox CC-DC and CC-P3 complement polymeric brominated flame retardants and are finding wide use as toxicity regulations become more stringent. United claims the new materials improve polymer degradation during performance, reduce the amount of heat generated and speed up self-extinguishing effects.
The Curox carbon-carbon initiators when used at a 0.2 percent level can lower the amounts of brominated flame retardants required. The additives trigger the chain-reaction burning process and support bromine radical formation.
United, based in Elyria, Ohio, says the new Curox grades are ecologically safe, do not migrate, are odorless, thermally stable and active at low dosage.
