Description

Dihexadecanoyl Peroxide is a high-purity organic peroxide compound widely recognized for its role 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 molecular weight development. This makes it an essential raw material for manufacturers in the polymer, plastics, and specialty chemical industries seeking reliable process control and product quality.

Application

• Polymerization Initiator: Primarily used as a free-radical initiator for the production of polyethylene (LDPE), polystyrene, and polyvinyl chloride (PVC).
• Cross-linking Agent: Employed in the cross-linking of elastomers and polyolefins to enhance thermal and mechanical properties.
• Curing Agent for Resins: Facilitates the curing process in unsaturated polyester resins and acrylic resins for composite materials.
• Synthesis Intermediate: Serves as a key intermediate in organic synthesis for introducing peroxide functional groups.
• Textile & Fiber Treatment: Used in chemical treatments to modify the surface properties of synthetic fibers.
• Adhesive & Coating Formulations: Acts as a curing agent in specific adhesive and coating systems requiring peroxide-initiated cross-linking.

Quality Control

Our Dihexadecanoyl Peroxide is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay by titration and identification by infrared spectroscopy (IR), to confirm identity and purity. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat sources, sparks, and open flame. Maintain storage temperature between 15°C and 25°C (59°F and 77°F). Keep away from incompatible materials such as reducing agents, strong bases, and heavy metal salts. Due to its nature as an organic peroxide, store separately in approved containers and in limited quantities as per local regulations.
