Trigonox 99-W50
Isopropylphenyl peroxydecanoate
CAS Number: 26748-47-0
Physical Form: Liquid
Trigonox® 99-W50 is a polymerization initiator used for the (co)polymerization of vinyl chloride and vinylidene chloride.
Applications
Trigonox® 99-W50 is used as an initiator for the suspension and bulk polymerization of vinyl chloride at temperatures between 40°C and 65°C. Trigonox® 99-W50 is typically used in combination with less active peroxides, such as peroxydicarbonates (e.g., Perkadox 16) or diacetyl peroxides (e.g., Laurox), to improve reactor efficiency. Water-based peroxide emulsions are used in place of solvent-based peroxides for the following reasons: improved safety, ease of use in “closed-reactor technology” (pumpable), and ease of dilution with water.
