Polymerization of vinyl chloride: Trigonox® EHP-W60 is applied as an initiator for the suspension polymerization of vinylchloride in the temperature range between 40°C and 65°C. Trigonox® EHP-W60 can be used 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. 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.
