Diacyl Peroxides are a fundamental class of organic peroxides widely used as low-to-medium temperature free-radical initiators in polymerization and curing processes. Characterized by their two acyl groups bonded to a peroxide linkage, they decompose readily to generate radicals, making them highly effective for initiating polymer chains and crosslinking networks.
Diacyl Peroxides are a fundamental class of organic peroxides that function as efficient low-to-medium temperature free-radical initiators in polymerization and curing systems. By decomposing to generate radicals under controlled thermal or chemical activation, they enable rapid chain initiation and crosslinking, which is essential for polymerization reactions and resin network formation. These products are widely used in industries requiring reliable initiation at moderate temperatures and precise control over curing kinetics.
We provide a focused portfolio of diacyl peroxides designed for polymerization initiation and resin curing across various material systems:
