Description

2-Butylazo-2-Propyl Hydroperoxide is a specialized organic peroxide initiator used in polymerization and chemical synthesis processes. This compound is valued for its ability to generate free radicals at moderate temperatures, making it a critical component for controlling reaction kinetics and polymer properties. It is primarily utilized by manufacturers in the polymer, resin, and specialty chemical industries seeking efficient and reliable initiation for high-quality production.

Application

• Primary free-radical initiator for the polymerization of vinyl monomers such as styrene, acrylates, and methacrylates.
• Used in the production of polystyrene (PS), acrylonitrile-butadiene-styrene (ABS), and other engineering plastics.
• Cross-linking agent for unsaturated polyester resins in the manufacture of fiberglass-reinforced plastics (FRP).
• Key component in the synthesis of specialty polymers and copolymers requiring controlled molecular weight and architecture.
• Used in organic synthesis as a source of alkoxy radicals for various chemical transformations.
• Applicable in the production of coatings, adhesives, and sealants where specific cure profiles are required.

Quality Control

Our 2-Butylazo-2-Propyl Hydroperoxide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed to confirm critical parameters such as active oxygen content, purity, and stability. Certificates of Analysis (COA) documenting full specifications are provided with every 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, well-ventilated area away from heat, sparks, and open flame. Due to its nature as an organic peroxide and being easily oxidized, it is recommended to store under an inert atmosphere where practical and to segregate from incompatible materials such as strong acids, reducing agents, and heavy metal compounds. Recommended storage temperature is 2-8°C (35-46°F) to maintain stability.
