Description

Di-tert-Butyl Peroxide is a high-purity organic peroxide widely recognized as a highly efficient free radical initiator and cross-linking agent. Its primary value lies in its ability to initiate polymerization reactions at elevated temperatures, making it indispensable for producing high-performance polymers and specialty chemicals. This compound is essential for manufacturers in the polymer, petrochemical, and specialty chemical synthesis industries seeking reliable and consistent reaction kinetics.

Application

• Polymerization Initiator: A key component for initiating the free-radical polymerization of ethylene, styrene, and other vinyl monomers to produce polyethylene, polystyrene, and various copolymers.
• Cross-linking Agent: Used to cross-link polyethylene, silicone rubbers, and other elastomers to enhance their thermal and mechanical properties.
• Organic Synthesis Intermediate: Serves as a source of tert-butoxy radicals in the synthesis of specialty chemicals, pharmaceuticals, and agrochemical intermediates.
• Fuel Additive: Employed as a cetane improver in diesel fuels to enhance ignition quality and combustion efficiency.
• Curing Agent for Resins: Facilitates the curing process for unsaturated polyester resins and acrylic resins in composite materials.
• Pyrolysis Aid: Used in analytical chemistry and industrial processes to study hydrocarbon pyrolysis and cracking mechanisms.

Quality Control

Our Di-tert-Butyl Peroxide is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay by GC, verification of peroxide content, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

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 as an organic peroxide and being easily oxidized (store under inert atmosphere) and highly volatile, it must be kept separate from reducing agents, strong acids, and combustible materials. Recommended storage temperature is below 30°C (86°F).
