Nouryon Perkadox 16-W40 Polymer Di(4-tert-butylcyclohexyl) peroxydicarbonate
Categories: Other Engineering Material
Material Notes: Initiator (40% active ingredient in water) for the production of PVC, PVA, PVOH and acrylics.

CAS number: 15520-11-3

EINECS/ELINCS No.: 239-557-1

Applications: Polymerization of vinyl chloride: Perkadox 16-W40 is applied as an initiator for the suspension polymerization of vinylchloride in the temperature range between 40°C and 65°C. Perkadox 16-W40 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 suspension instead of a solid or solvent-based peroxide are the following: enhanced safety, solvent free. No contamination of the VCM recycle stream, enhancement of PVC purity, easy to use (pumpable) in ‘closed reactor technology’, easy to dilute with water.
