Description

Dipropionyl Peroxide (in Solution, Content ≤27%) is a powerful organic peroxide initiator widely used in industrial polymerization processes. Its controlled decomposition at moderate temperatures makes it a critical component for initiating free-radical reactions with high efficiency and reliability. This product is essential for manufacturers in the polymer and resin industries seeking to optimize production cycles and enhance material properties.

Application

• Polymerization Initiator: Primary use as a free-radical initiator for the production of polyvinyl chloride (PVC), low-density polyethylene (LDPE), and polystyrene (PS).
• Cross-linking Agent: Used in the curing and cross-linking of unsaturated polyester resins and acrylic resins for composites and coatings.
• Synthesis Intermediate: Serves as a key reagent in organic synthesis for introducing peroxide functional groups.
• Curing Agent for Elastomers: Facilitates the vulcanization and curing of silicone and other specialty rubbers.
• Modifier for Polymer Properties: Employed to control molecular weight and branching during polymer manufacturing to achieve specific performance characteristics.

Quality Control

Our Dipropionyl Peroxide solution is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay by iodometric titration and verification of active oxygen content. A detailed Certificate of Analysis (COA) documenting purity, solvent content, and critical safety parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Recommended storage temperature is between 2°C and 8°C (35°F - 46°F) to maintain stability. Keep separated from incompatible materials such as reducing agents, strong acids, bases, and metals. Containers must be clearly labeled and handled with appropriate personal protective equipment.
