Description

tert-Butyl Peroxyneoheptanoate is a high-purity organic peroxide initiator widely used in industrial polymerization processes. Its primary value lies in its ability to efficiently generate free radicals at specific temperature ranges, enabling precise control over polymer molecular weight and structure. This product is essential for manufacturers in the plastics and synthetic rubber industries seeking to optimize production efficiency and final product properties.

Application

• Polymerization Initiator: A key free-radical initiator for the production of polyvinyl chloride (PVC), low-density polyethylene (LDPE), and polystyrene (PS).
• Cross-linking Agent: Used in the curing and cross-linking of unsaturated polyester resins for fiberglass-reinforced plastics and coatings.
• Synthetic Rubber Production: Employed in the polymerization of styrene-butadiene rubber (SBR), ethylene-propylene-diene monomer (EPDM), and other elastomers.
• Acrylic Resin Synthesis: Facilitates the polymerization of methyl methacrylate (MMA) and other acrylic monomers for adhesives, paints, and coatings.
• Modifier for Polymer Properties: Helps control branching and molecular weight distribution to achieve desired mechanical and thermal properties in finished polymers.
• Curing Agent for Composites: Used in the manufacture of composite materials requiring controlled, heat-activated curing cycles.

Quality Control

Our tert-Butyl Peroxyneoheptanoate is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including assay by HPLC and gas chromatography (GC), to verify purity and active oxygen content. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance protocols.

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 strong acids, bases, reducing agents, and other organic compounds. Due to its highly volatile and strong oxidizing nature, store separately in a dedicated, approved area for peroxides.
