Description

Di-3-Methyl-3-Methoxybutyl Peroxy Dicarbonate is a specialized organic peroxide initiator used in polymerization processes. This compound is valued for its ability to decompose at moderate temperatures, generating free radicals essential for initiating and controlling the polymerization of monomers like vinyl chloride. It is a critical component for manufacturers in the polymer and plastics industries seeking to produce high-quality PVC resins and other specialty polymers with controlled molecular weight and structure.

Application

• Primary Initiator for PVC Suspension Polymerization: Widely used in the production of polyvinyl chloride (PVC) resins, controlling the reaction kinetics and final polymer properties.
• Co-initiator in Copolymer Systems: Employed in combination with other initiators to tailor the polymerization rate and molecular weight distribution in copolymer production.
• Manufacture of Specialty Polymers: Facilitates the synthesis of specific grades of polymers requiring precise initiation profiles and low-temperature activity.
• Cross-linking Agent: Used in applications where peroxide-induced cross-linking of polymers is required to enhance material properties.
• Production of Polymer Dispersions: Applicable in emulsion and suspension processes for creating fine polymer particles used in coatings, adhesives, and sealants.

Quality Control

Our Di-3-Methyl-3-Methoxybutyl Peroxy Dicarbonate is manufactured under strict quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed for critical parameters including active oxygen content, purity, and stability. A comprehensive Certificate of Analysis (COA) detailing assay results and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

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 below 25°C (77°F). Keep away from incompatible materials such as reducing agents, strong acids, bases, and heavy metal compounds. Due to its nature as an organic peroxide, store in the original container and avoid contamination.
