Description

Di-tert-Amyl Peroxide is a highly effective organic peroxide primarily utilized as a polymerization initiator and crosslinking agent. Its controlled decomposition characteristics make it a critical component for initiating free-radical reactions in polymer synthesis. This compound is essential for manufacturers in the plastics, rubber, and specialty chemical industries seeking to produce high-performance materials with specific molecular architectures.

Application

• Polymerization Initiator: Used to initiate the free-radical polymerization of monomers such as ethylene, styrene, and vinyl chloride for the production of various plastics and resins.
• Crosslinking Agent: Employed in the crosslinking of polyethylene, silicone rubbers, and other elastomers to enhance thermal stability and mechanical properties.
• Curing Agent for Unsaturated Polyester Resins: Facilitates the room-temperature or elevated-temperature curing of fiberglass-reinforced plastics (FRP) and composite materials.
• Organic Synthesis Intermediate: Serves as a source of tert-amyloxy radicals in specialized organic synthesis reactions.
• Modifier for Polymer Properties: Used to control molecular weight and branching during polymer production to achieve desired material characteristics.
• Adhesive and Coating Formulations: Incorporated into formulations where controlled, radical-induced curing is required for coatings and adhesives.

Quality Control

Our Di-tert-Amyl Peroxide is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay by GC or HPLC and verification of peroxide content. A Certificate of Analysis (COA) detailing purity, identity, and key physical parameters is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) at temperatures not exceeding 25°C (77°F). Keep away from incompatible materials such as strong acids, reducing agents, and heavy metal compounds. Follow all local and international regulations for storing organic peroxides.
