Description

tert-Butyl Isononaneperoxoate is a high-purity organic peroxide used as a key initiator in polymerization reactions. Its primary value lies in its ability to efficiently generate free radicals under controlled thermal conditions, enabling the production of polymers with specific molecular weights and properties. This product is essential for manufacturers in the plastics, rubber, and specialty chemical industries seeking reliable and consistent polymerization performance.

Application

• Polymerization Initiator: A critical component for the free-radical polymerization of monomers such as ethylene, styrene, vinyl chloride, and acrylates.
• Crosslinking Agent: Used in the curing and crosslinking processes for unsaturated polyester resins and certain elastomers.
• Synthetic Rubber Production: Employed in the manufacture of styrene-butadiene rubber (SBR) and other synthetic rubbers.
• High-Pressure LDPE Production: Serves as an initiator in the high-pressure tubular or autoclave processes for low-density polyethylene (LDPE).
• Acrylic Resin Synthesis: Facilitates the polymerization of methyl methacrylate (MMA) and other acrylic monomers.
• Chemical Intermediate: Used in organic synthesis for the introduction of peroxy functional groups.

Quality Control

Our tert-Butyl Isononaneperoxoate is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, active oxygen content, and impurity profiles. Certificates of Analysis (COA) documenting these results are provided to guarantee traceability, consistency, and compliance with your process requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep away from reducing agents, strong acids, bases, and combustible materials. Recommended storage temperature is below 25°C (77°F). This product is a light-sensitive (store away from light) strong oxidizer and requires appropriate segregation.
