  • Applications

    Polymerization of vinyl chloride - Trigonox EHP-W50 is applied as an initiator for the suspension polymerization of vinylchloride in the temperature range between 40°C and 65°C. Trigonox EHP-W50 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 safetyeasy to use (pumpable) in ‘closed reactor technology’easy to dilute with water.
