Description

Bis-(2-Ethylhexanoyl) Peroxide is a highly effective organic peroxide widely used as a polymerization initiator and crosslinking agent. Its primary value lies in its ability to generate free radicals at moderate temperatures, making it crucial for controlling reaction kinetics in polymer synthesis. This compound is essential for manufacturers in the plastics, rubber, and coatings industries seeking to produce high-performance materials with specific properties.

Application

• Primary initiator for the polymerization of vinyl chloride (PVC) and other vinyl monomers.
• Key component in the curing and crosslinking of unsaturated polyester resins for fiberglass-reinforced plastics (FRP).
• Used as a crosslinking agent for silicone rubbers and polyethylene to enhance thermal and mechanical properties.
• Employed in the production of acrylic resins and polystyrene, influencing molecular weight and polymer structure.
• Facilitates the manufacture of specialty adhesives and coatings requiring controlled cure profiles.
• Applied in the synthesis of modified plastics and elastomers for automotive and construction applications.

Quality Control

Our Bis-(2-Ethylhexanoyl) Peroxide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, active oxygen content, and impurity profiles. Certificates of Analysis (COA) documenting these results are provided to guarantee consistency and performance for your critical polymerization 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 nature 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 other peroxides. Recommended storage temperature is 15-25°C.
