Description

[Isopropylidenedicyclohexane-4,1-Diyl]Bis(tert-Butyl) Peroxide is a high-purity, symmetrical dialkyl peroxide initiator. This compound matters for industrial processes requiring a reliable and efficient source of free radicals for polymerization and cross-linking reactions at elevated temperatures. It is primarily needed by manufacturers in the polymer and specialty chemical industries for producing materials like high-performance plastics, elastomers, and resins.

Application

• Polymerization Initiator: Used as a free-radical initiator for the bulk or suspension polymerization of styrene, ethylene, and other vinyl monomers.
• Cross-Linking Agent: Essential for the cross-linking (curing) of polyethylene, silicone rubbers, and other polymers to enhance thermal and mechanical properties.
• Synthesis of Specialty Polymers: Facilitates the production of high-performance engineering plastics and block copolymers with specific structural characteristics.
• Organic Synthesis Intermediate: Serves as a key reagent in controlled radical reactions and the synthesis of complex organic molecules.
• Elastomer Manufacturing: Employed in the vulcanization process for synthetic rubbers to improve durability and chemical resistance.
• Resin Production: Acts as a curing agent for unsaturated polyester resins used in composites and fiberglass.

Quality Control

Our [Isopropylidenedicyclohexane-4,1-Diyl]Bis(tert-Butyl) Peroxide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay and impurity profile analysis, to ensure it meets precise specifications for use as a polymerization initiator. Certificates of Analysis (COA) documenting purity, active oxygen content, and other critical parameters are available upon request to support your quality assurance protocols.

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 a peroxide and being highly volatile, it must be kept separate from reducing agents, acids, bases, and combustible materials. Recommended storage temperature is below 30°C (86°F).
