Perkadox® 14S

Technical Datasheet | Supplied by Nouryon
Di(2-tert-butylperoxyisopropyl)benzene. Used as a initiator for the (co)polymerization of styrene and the production of controlled rheology polypropylene and coagent in flame retardant polystyrene formulations. High melt flow index polypropylene grades are produced by post reactor treatment. Possesses high flexibility. The peroxide concentration controls the final viscosity. As thermally unstable substance, it may undergo self accelerating decomposition. Exhibits very low volatility.

Hansen Solubility Parameters

[15.7, 2.9, 5.3]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Perkadox® 14S. A practical determination of these HSP values would provide higher certainty. Learn More.
