What Is Cumyl hydroperoxide?
Cumyl hydroperoxide is a hydroperoxide supplied under the Perodox brand as part of the
Organic Peroxides – Hydroperoxides portfolio. High-purity cumyl hydroperoxide used as a polymerization initiator for styrene and acrylonitrile. Widely applied in ABS resin and styrene-butadiene rubber production. As a polymerization initiator,
it is engineered for demanding Polymer Production, Rubber and Elastomers applications where consistency and purity are critical.
Key Properties & Specifications
- Chemical family: Hydroperoxide
- CAS number: 80-15-9
- Physical form: Liquid
- Decomposition temperature: 80-90°C
- Active oxygen content: 8.2%
- Molecular weight: 152.19
How It Works
As an organic peroxide, Cumyl hydroperoxide decomposes by homolytic cleavage when heated near 80-90°C, 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.
Primary Applications
Perodox K is applied across ABS, Polystyrene, Acrylic Resin, Rubber Crosslinking. Typical market segments include Polymer Production, Rubber and Elastomers.
Its performance profile makes it a trusted choice for formulators who need reproducible,
