Decanoyl peroxide

Decanoyl peroxide (CAS 762-12-9), also known as didecanoyl peroxide, is an organic peroxide used as a free-radical source in polymer manufacturing and curing processes.

Where is Decanoyl peroxide used?

• Plastics and polymer production: initiates free-radical polymerization of vinyl and acrylic monomers, allowing control of molecular weight and reaction rate
• Rubber compounding: curing agent that cross-links elastomers
• Coatings: hardener or initiator in peroxide-cured systems requiring thermal activation
• Adhesives and sealants: incorporated into peroxide-cured systems where controlled gel time and bond strength are critical
• It decomposes at controlled temperatures to generate radicals that initiate polymerization or drive cross-linking reactions.

Commercial specifications

• Technical grade is the standard commercial form; active oxygen content is the primary specification for quality control
• Typically packaged and stored under temperature-controlled conditions to maintain stability
• Suppliers commonly offer formulated blends to suit specific cure profiles
