Physical form: Emulsion
Trigonox® 187-W40 is a polymerization initiator (co-)polymerization of vinyl chloride and vinylidene chloride for the production of PVC.
Vinyl chloride polymerization: Trigonox® 187-W40 is an extremely reactive initiator developed for the low temperature polymerization of vinyl chloride for the production of high K-value PVC. Trigonox® 187-W40 can also be used in combination with other peroxides, e.g. di(2-ethylhexyl) peroxydicarbonate (Trigonox® EHP), to improve reactor efficiency.
