Applications

Application	Description
Polymerization of Vinyl Chloride	Widely used in water-phase suspension and bulk polymerization reactions, with temperature range between 60-75℃. Often combined with other high-activity peroxides to enhance reactivity.
Polymerization of Ethylene	Used in high-pressure polymerization, but often replaced by peroxynonanoates due to solubility issues. Its key advantage is room-temperature storage.
Polymerization of Acrylates and Methacrylates	Can be used in acrylate polymerization reactions at 60-90℃, often replacing more toxic initiators like azobisisobutyronitrile.
ABS Resin Polymerization Initiator	Important initiator in ABS polymerization, often used in combination with LQ-CH335 for enhanced initiation efficiency.
