We offer a wide range of organic peroxide initiators for the production of general purpose polystyrene (GPPS), high impact polystyrene (HIPS), expandable polystyrene (EPS) and other styrenic copolymers. Initiators are available for mass and suspension polymerization processes.

Organic peroxide initiators are also used for the production of other styrenic copolymers such as styrene acrylonitrile (SAN), polymer polyols and toner resins. Hydroperoxides are mainly applied in styrene butadiene rubber (SBR) and acrylonitrile butadiene styrene (ABS) emulsion processes.

Peroxide initiator benefits, when compared to thermal initiation, include increased reactor output, tailored molecular weight and lower levels of monomer and oligomer residuals.

Our well-known brands Perkadox® 30 and Perkadox BC are extensively used as flame retardant synergists, mainly in EPS.
