Description

Dioxybis(1-Methylpropylidene) Hydroperoxide is a specialized organic peroxide compound widely utilized as a high-performance initiator in polymerization reactions. Its primary commercial value lies in its ability to efficiently generate free radicals at moderate temperatures, enabling controlled polymer synthesis and cross-linking processes. This product is essential for manufacturers in the polymer, resin, and specialty chemical industries seeking reliable and effective initiators for producing materials like polyvinyl chloride (PVC), unsaturated polyesters, and acrylic resins.

Application

• Polymerization Initiator: A key free-radical initiator for the bulk, suspension, and solution polymerization of vinyl monomers such as vinyl chloride, styrene, and acrylates.
• Resin Curing Agent: Used in the cross-linking and curing of unsaturated polyester resins (UPR) for fiberglass-reinforced plastics (FRP), coatings, and composite materials.
• Synthetic Rubber Production: Employed in the production of synthetic rubbers like styrene-butadiene rubber (SBR) and other elastomers.
• Acrylic Polymer Synthesis: Facilitates the manufacture of poly(methyl methacrylate) (PMMA) and other acrylic polymers for sheets, molding compounds, and adhesives.
• Chemical Intermediate: Serves as a reactive intermediate in organic synthesis for introducing peroxide functionalities.
• Cross-linking Agent for Polyolefins: Used in the modification and cross-linking of polyethylene (PE) and other polyolefins to enhance thermal and mechanical properties.

Quality Control

Our production of Dioxybis(1-Methylpropylidene) Hydroperoxide adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed against established specifications for purity, active oxygen content, and impurity profiles. Certificates of Analysis (COA) documenting these results are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its nature as an organic peroxide and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) when in partially used containers. Keep away from incompatible materials such as strong acids, reducing agents, and heavy metal compounds. Recommended storage temperature is 15-25°C.
