CAS number: 15520-11-3

EINECS/ELINCS No.: 239-557-1

Applications: Polymer production: Polymerization of vinyl chloride Perkadox 16 is applied as an initiator for the suspension and mass polymerization of vinyl chloride in the temperature range between 40°C and 65°C. Perkadox 16 can be used alone or in combination with other peroxides, such as 1,1,3,3-Tetramethylbutyl peroxyneodecanoate (Trigonox 423), Cumyl peroxyneodecanoate (Trigonox 99) or Dilauroyl peroxide (Laurox), to increase reactor efficiency. For Thermoset: Perkadox 16 is a solid peroxydicarbonate which is used for the curing of unsaturated polyester resins and methacrylic resins mainly in the temperature range of 60°C and higher. Perkadox 16 is not suitable for the production of clear - castings or - coatings, due to a slight haze in the end product. In this case, Perkadox 16S can be advised. Perkadox 16 shows a high reactivity at elevated temperatures, which is demonstrated by its low activation temperature, in combination with a relatively long pot life at ambient temperatures. Perkadox 16 is mostly used in combination with a low reactive peroxide to ensure a good final cure. Combinations of Perkadox 16 with e.g. Trigonox C, Trigonox 29-B50 or Trigonox 21 can therefore successfully be used for those applications where a long gel time or production time is required at room temperature in combination with a fast cure at elevated temperatures of e.g. 60-140°C. Applications area can be: pultrusion, filament winding, manufacturing of artificial marble.
