Key Properties & Specifications
- Chemical family: Acyl Peroxide
- CAS number: 94-36-0
- Physical form: Solid
- Decomposition temperature: 70-80°C (room temp cure)
- Active oxygen content: 6.6%

How It Works
As an organic peroxide, Dibenzoyl peroxide (BPO) decomposes by homolytic cleavage when heated near 70-80°C (room temp cure), generating free radicals. These radicals initiate the polymerization or crosslinking of unsaturated monomers (such as styrene, acrylates, vinyls and unsaturated polyester resins), making it a core radical initiator for thermoset and polymer manufacturing.
