Description

Di-tert-Butyl Diperoxyazelate is a high-purity organic peroxide widely used as a crosslinking agent and initiator in polymer chemistry. Its primary value lies in its ability to efficiently generate free radicals under controlled thermal conditions, enabling the synthesis and modification of high-performance polymers. This compound is essential for manufacturers in the plastics, rubber, and specialty chemical industries seeking to enhance material properties such as thermal stability, elasticity, and durability.

Application

• Polymer Crosslinking Agent: Key for curing and crosslinking unsaturated polyester resins (UPR) and vinyl ester resins in the production of fiberglass-reinforced plastics (FRP), coatings, and laminates.
• Rubber Vulcanization: Used as a co-agent in the peroxide-cure systems for ethylene-propylene-diene monomer (EPDM), silicone rubber, and other elastomers to improve heat resistance and compression set.
• Polymer Modification: Initiator for the grafting and functionalization of polyolefins (e.g., polyethylene, polypropylene) to improve adhesion, compatibility, and other surface properties.
• Thermoset Resin Production: Serves as a curing initiator in the manufacture of thermoset composites for automotive, marine, and construction applications.
• Synthesis Intermediate: Employed in organic synthesis as a source of tert-butoxy radicals for various oxidation and functionalization reactions.

Quality Control

Our Di-tert-Butyl Diperoxyazelate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by iodometric titration and purity verification by HPLC, to ensure it meets precise specifications for active oxygen content and impurity profiles. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to guarantee supply reliability and batch-to-batch consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. 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, strong bases, reducing agents, and other peroxides. Recommended storage temperature is 15-25°C. This product is highly volatile; ensure containers are kept tightly sealed when not in use.
