Description

Diheptadecanoyl Peroxide is a high-purity organic peroxide compound, serving as a critical initiator and cross-linking agent in advanced polymer synthesis. Its controlled decomposition properties are essential for driving free-radical polymerization reactions with precision and efficiency. This specialty chemical is vital for manufacturers in the polymer, plastics, and specialty materials industries seeking to enhance product performance and process control.

Application

• Polymerization Initiator: A key free-radical initiator for the production of polyethylene (LDPE), polyvinyl chloride (PVC), polystyrene (PS), and other vinyl polymers.
• Cross-linking Agent: Used to create cross-linked polymers for wire and cable insulation, heat-shrinkable tubing, and elastomers to improve thermal and mechanical properties.
• Silicone Rubber Curing: Employed in the vulcanization (peroxide cure) of high-temperature silicone rubbers for automotive, aerospace, and industrial gaskets and seals.
• Unsaturated Polyester Resin (UPR) Curing: Facilitates the room-temperature or elevated-temperature curing of fiberglass-reinforced plastics (FRP) for marine, construction, and automotive components.
• Acrylic Resin Production: Acts as an initiator in the synthesis of acrylic resins and polymethyl methacrylate (PMMA) for coatings, adhesives, and optical applications.
• Specialty Chemical Synthesis: Utilized in organic synthesis as an oxidizing agent or radical source for creating fine chemicals and pharmaceutical intermediates.

Quality Control

Our Diheptadecanoyl Peroxide is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, purity, and active oxygen content determination. A Certificate of Analysis (COA) documenting all critical parameters 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, well-ventilated area away from heat, sparks, and open flame. Maintain at controlled room temperature (15-25°C). Isolate from incompatible materials such as reducing agents, strong bases, and combustible materials. Due to its nature as a peroxide, monitor shelf life and storage conditions regularly.
