Description

tert-Butyl Octaneperoxoate is an organic peroxide compound widely utilized as a high-efficiency initiator for polymerization reactions. Its primary value lies in its ability to generate free radicals at controlled temperatures, enabling precise and efficient polymer synthesis. This makes it a critical raw material for manufacturers in the polymer, plastics, and specialty chemical industries seeking to produce materials with specific molecular weights and properties.

Application

• Primary free-radical initiator for the polymerization of ethylene, styrene, and (meth)acrylates.
• Key component in the production of low-density polyethylene (LDPE) and other thermoplastic resins.
• Cross-linking agent for elastomers and silicone rubbers to enhance thermal and mechanical properties.
• Used in the synthesis of acrylic resins for coatings, adhesives, and sealants.
• Essential for manufacturing polystyrene and expandable polystyrene (EPS) foams.
• Applied in the curing processes for unsaturated polyester resins (UPR) in composite materials.

Quality Control

Our tert-Butyl Octaneperoxoate is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profiling, to ensure it meets precise specifications for active oxygen content and purity. Certificates of Analysis (COA) documenting all critical parameters are provided to guarantee batch-to-batch consistency and performance reliability for your processes.

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, it is recommended to store under an inert atmosphere where practical. Keep away from incompatible materials such as strong acids, reducing agents, and heavy metal compounds. Recommended storage temperature is below 25°C (77°F).
