Description

3,3’,4,4’-Tetra(T-Butyl Peroxycarbonate) Benzophenone is a specialized high-performance organic peroxide derivative of benzophenone. This compound is valued for its role as a highly efficient free-radical initiator and cross-linking agent in advanced polymer synthesis. It is primarily required by manufacturers in the polymer, specialty chemical, and advanced materials industries seeking to enhance the thermal and mechanical properties of their products.

Application

• Polymerization Initiator: Acts as a key free-radical initiator for the production of high-performance polymers, including polyethylene (PE), polypropylene (PP), and polystyrene (PS).
• Cross-linking Agent: Used to create cross-linked polymer networks in silicone rubbers, polyethylene wire & cable insulation, and other elastomers to improve heat resistance and durability.
• Curing Agent for Composites: Employed in the curing of unsaturated polyester resins and vinyl ester resins for fiber-reinforced plastics (FRP) used in automotive and marine applications.
• Synthesis of Specialty Chemicals: Serves as an intermediate in the synthesis of photoinitiators, pharmaceuticals, and other fine chemicals requiring controlled radical reactions.
• Modifier for Polymer Properties: Utilized to control molecular weight and branching during polymerization, tailoring the melt flow and impact strength of engineering plastics.

Quality Control

Our production of 3,3’,4,4’-Tetra(T-Butyl Peroxycarbonate) Benzophenone adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, purity verification, and active oxygen content determination, to ensure consistency and performance reliability. Certificates of Analysis (COA) documenting all critical parameters are available upon request 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 a strong oxidizer and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) and separate from incompatible materials such as reducing agents, strong acids, and bases. Recommended storage temperature is 15-25°C.
