Description

Bisdecanoyl Peroxide is an organic peroxide compound widely utilized as a polymerization initiator and cross-linking agent. Its controlled decomposition properties are critical for initiating free-radical reactions in polymer synthesis, ensuring consistent and predictable reaction kinetics. This makes it an essential raw material for manufacturers in the plastics, rubber, and specialty chemical industries seeking reliable process control and high-quality polymer outputs.

Application

• Polymerization Initiator: Primarily used for the free-radical polymerization of monomers such as vinyl chloride, styrene, and acrylates to produce PVC, polystyrene, and acrylic resins.
• Cross-linking Agent: Employed in the vulcanization and curing of silicone rubbers and certain polyethylene compounds to enhance thermal and mechanical properties.
• Unsaturated Polyester Resin Curing: Acts as a catalyst for curing unsaturated polyester resins (UPR) in the production of fiberglass-reinforced plastics (FRP) and composite materials.
• Chemical Synthesis Intermediate: Serves as an intermediate in organic synthesis for introducing peroxy functional groups.
• Adhesive & Coating Formulations: Used in formulations for specific adhesives and radiation-curable coatings where peroxide initiation is required.

Quality Control

Our Bisdecanoyl Peroxide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, active oxygen content, and stability. A Certificate of Analysis (COA) detailing assay results, impurity profiles, and physical characteristics is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat, sparks, and open flames. Maintain storage temperature below 25°C (77°F). Isolate from reducing agents, strong bases, acids, and combustible materials. Due to its nature as an organic peroxide, do not store in large quantities and keep containers tightly sealed to prevent moisture absorption and decomposition.
