Description

1,1'-Azobis(Cyclooctanecarbonitrile) is a high-purity, low-temperature azo initiator widely used in free-radical polymerization processes. Its primary value lies in its ability to efficiently generate free radicals at moderate temperatures, enabling precise control over polymer molecular weight and structure. This compound is essential for manufacturers in the polymer and specialty chemical industries, particularly for producing high-performance acrylics, styrenics, and other specialty resins where controlled initiation is critical.

Application

• Polymer Synthesis: As a primary initiator for the free-radical polymerization of vinyl monomers such as methyl methacrylate (MMA), styrene, and acrylonitrile.
• Specialty Resin Production: For manufacturing acrylic resins, polystyrene, and ABS (Acrylonitrile Butadiene Styrene) with controlled molecular weight distributions.
• Cross-linking Agent: Used in the production of cross-linked polymers and coatings to enhance thermal and mechanical properties.
• Foam Manufacturing: Acts as a blowing agent initiator in the production of certain polymer foams.
• Adhesive & Sealant Formulation: A key component in the synthesis of polymers for high-performance adhesives and sealants.
• Research & Development: Employed in laboratory-scale polymer research for studying polymerization kinetics and mechanisms.

Quality Control

Our 1,1'-Azobis(Cyclooctanecarbonitrile) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistent performance as a polymerization initiator. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flames. Due to its light-sensitive nature, containers should be kept in the original packaging or in opaque containers until use.
