Initiator for (co)polymerization of vinyl chloride and vinylidene chloride.
Africa, Europe, India, Middle East
Perkadox 24-W35 is applied as an initiator in the suspension polymerization of vinylchloride in the temperature range between 45°C and 65°C. Perkadox 24-W35 may 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. Perkadox 24-W35 is suitable for the manufacture of plastics for food contact applications. 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. Perkadox 24-W35 contains a minimum of surfactants, and these are carefully selected so as not to influence the properties of the PVC produced.
