Description

1,1'-Azobis(2-Methylcyclohexanecarbonitrile) is a versatile and highly efficient azo-type polymerization initiator. Its primary value lies in its ability to decompose at moderate temperatures to generate free radicals, initiating and controlling the polymerization of vinyl monomers. This compound is essential for manufacturers in the polymer and plastics industries, particularly for the production of specialty resins, coatings, and high-performance elastomers where controlled molecular weight and polymer architecture are critical.

Application

• Free Radical Polymerization Initiator: Primary use for polymerizing styrene, acrylates, methacrylates, and other vinyl monomers.
• Production of Acrylic Resins & Plastics: Used in the synthesis of PMMA (polymethyl methacrylate), polystyrene, and ABS (acrylonitrile butadiene styrene) resins.
• Manufacture of Specialty Coatings & Adhesives: Initiates cross-linking reactions in UV-curable coatings, pressure-sensitive adhesives, and industrial finishes.
• Synthesis of Synthetic Rubbers & Elastomers: Key component in the production of nitrile rubber (NBR) and other synthetic elastomers.
• Foam Manufacturing: Acts as a blowing agent or co-initiator in the production of polymeric foams.
• Cross-linking Agent for Polymers: Used to create cross-linked polymer networks for enhanced thermal and mechanical properties.
• Research & Development: Serves as a model initiator in academic and industrial R&D for studying polymerization kinetics and mechanisms.

Quality Control

Our 1,1'-Azobis(2-Methylcyclohexanecarbonitrile) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, consistent performance, and compliance with industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and product integrity for your polymerization processes.

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, open flames, and incompatible materials. Due to its light-sensitive nature, containers must be kept in the original packaging or opaque containers until use.
