Nouryon Trigonox 99-W50 Cumyl peroxyneodecanoate
Categories:	Other Engineering Material
Material Notes:	Initiator (75% active ingredient in water) for (co)polymerization of vinyl chloride and vinylidine chloride. CAS number: 26748-47-0 EINECS/ELINCS No: 247-956-7 Applications: Trigonox 99-W50 is used as an initiator for the suspension and mass polymerization of vinyl chloride between 40°C and 65°C. Trigonox 99-W50 is often combined with less active peroxides such as peroxydicarbonates (e.g. Perkadox 16) or diacylperoxides (e.g. Laurox) to increase reactor efficiency. Reasons to use a water-based peroxide emulsion instead of a solvent-based peroxide are the following: enhanced safety, easy to use (pumpable) in ‘closed reactor technology’, easy to dilute with water Information provided by Nouryon
