Collection: Thermal Polymerization Initiators

Thermal Polymerization Initiators — contains peroxide, azo, and phosphonium or sulfonium salt compounds that decompose under heat to generate free radicals that trigger polymerization reactions. This group is a basic component in controlling the rate and initial temperature of free radical polymerization reactions.

Thermal Polymerization Initiators are used by polymer chemistry researchers and the materials industry to initiate free radical polymerization in the production of resins, adhesives, and composite materials, with adjustable activation temperatures. Compounds such as Benzoyl Peroxide and tert-Butyl Hydroperoxide are also used in emulsion copolymerization reactions and thermal curing processes.
