it is engineered for demanding Polymer Production, Rubber and Elastomers applications where consistency and purity are critical.
Key Properties & Specifications
- Chemical family: Alkyl Peroxide
- CAS number: 110-05-4
- Physical form: Liquid
- Decomposition temperature: 130-175°C
- Active oxygen content: 10.9%
- Molecular weight: 146.23
How It Works
As an organic peroxide, Di-tert-butyl peroxide (DTBP) decomposes by homolytic cleavage when heated near 130-175°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 B is applied across Acrylic Resin, PP, LDPE, EVA, Rubber Crosslinking. Typical market segments include Polymer Production, Rubber and Elastomers.
Its performance profile makes it a trusted choice for formulators who need reproducible,
high-purity raw materials.
