Description

Bis(2-Ethylhexyl) Diperoxycarbonate is a high-purity organic peroxide widely utilized as a polymerization initiator and crosslinking agent. Its primary value lies in its ability to decompose at moderate temperatures to generate free radicals, making it essential for controlling polymer chain growth and structure. This compound is critically needed by manufacturers in the polymer, plastics, and specialty chemical industries for producing materials with specific mechanical and thermal properties.

Application

• Primary initiator for the polymerization of vinyl chloride (PVC), ethylene, styrene, and acrylates.
• Crosslinking agent for unsaturated polyesters and silicone rubbers, enhancing heat and chemical resistance.
• Used in the production of expandable polystyrene (EPS) and other foam plastics.
• Key component in the synthesis of high-performance acrylic resins and coatings.
• Facilitates curing reactions in fiber-reinforced composites for automotive and aerospace applications.
• Employed in the manufacture of optical materials and specialty adhesives requiring precise curing profiles.

Quality Control

Our Bis(2-Ethylhexyl) Diperoxycarbonate is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, active oxygen content, and stability. Certificates of Analysis (COA) documenting these results are available for 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. Due to its properties as an organic peroxide and being easily oxidized, it is recommended to store under an inert atmosphere when in opened containers. Keep separated from incompatible materials such as strong acids, reducing agents, and other accelerators. Recommended storage temperature is below 25°C (77°F).
