Trigonox 99-W50 is a polymerization initiator for (co)polymerization of vinyl chloride and vinylidene chloride.
Asia Pacific, Latin America, North America
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
