Description

2,2'-Azodi(2-Methylbutyronitrile) is a highly efficient, low-temperature azo initiator widely used in free-radical polymerization processes. Its primary value lies in its ability to generate free radicals at moderate temperatures, enabling precise control over polymer molecular weight and structure. This compound is essential for manufacturers in the polymer, plastics, and specialty chemical industries seeking to produce high-quality acrylics, vinyl polymers, and other synthetic resins.

Application

• Primary initiator for the polymerization of vinyl chloride, acrylonitrile, and methyl methacrylate.
• Key component in the production of expandable polystyrene (EPS) and other foam plastics.
• Used in the synthesis of acrylic resins for coatings, adhesives, and sealants.
• Essential for manufacturing high-impact polystyrene (HIPS) and acrylonitrile butadiene styrene (ABS) resins.
• Employed in the curing process for unsaturated polyester resins.
• Facilitates graft copolymerization reactions in advanced material development.
• Used in the production of synthetic rubber and elastomers.
