Description

Diphenylethane Hydroperoxide is an organic peroxide compound widely utilized as a polymerization initiator and cross-linking agent. Its primary value lies in its ability to generate free radicals under thermal conditions, making it essential for initiating and controlling polymer chain reactions. This product is critical for manufacturers in the polymer, resin, and specialty chemical industries seeking efficient and reliable initiators for high-performance materials.

Application

• Primary polymerization initiator for the production of styrene-based polymers and copolymers.
• Key component in the curing and cross-linking of unsaturated polyester resins for composites and coatings.
• Used in the synthesis of specialty thermosetting plastics and high-impact materials.
• Employed as a radical source in organic synthesis for creating carbon-carbon bonds.
• Facilitates the production of adhesives and sealants requiring controlled cure profiles.
• Applied in the manufacture of rubber modifiers and elastomer products.

Quality Control

Our Diphenylethane Hydroperoxide is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, activity, and stability. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with every shipment to guarantee traceability and compliance with your process requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, sparks, and open flame. Due to its nature as an organic peroxide and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) when in partially used containers. Keep away from strong acids, bases, reducing agents, and other incompatible materials. Recommended storage temperature is 2-8°C for long-term stability.
