Description

Dibutyryl Peroxide is a highly reactive organic peroxide compound, primarily valued for its role as a polymerization initiator and cross-linking agent. Its controlled decomposition into free radicals is critical for initiating and controlling chain-growth reactions in polymer synthesis. This makes it an essential raw material for manufacturers in the polymer and plastics industries, particularly for producing specialized resins, elastomers, and other high-performance materials where precise initiation kinetics are required.

Application

• Polymerization Initiator: A key catalyst for the free-radical polymerization of monomers like vinyl chloride, styrene, and acrylates to produce various plastics and resins.
• Cross-linking Agent: Used to create three-dimensional polymer networks, enhancing the thermal and mechanical properties of silicone rubbers, polyethylene, and other polymers.
• Curing Agent for Unsaturated Polyester Resins: Facilitates the room-temperature or heat-activated curing process in fiberglass-reinforced plastics (FRP) and composite materials.
• Organic Synthesis Intermediate: Employed in specific chemical synthesis processes that require a source of butyryl or peroxy radicals.
• Modifier for Polymer Properties: Used to control molecular weight and branching during polymer production, tailoring final product characteristics.

Quality Control

Our Dibutyryl Peroxide is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, activity, and stability. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and other critical parameters is provided with every shipment to guarantee batch-to-batch consistency and support your quality assurance protocols.

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 a peroxide and being highly volatile, it must be segregated from reducing agents, acids, bases, and combustible materials. Recommended storage temperature is below 25°C (77°F).
