Overview of Dicumyl Peroxide

Dicumyl Peroxide is an organic peroxide extensively used as a crosslinking ingredient and a free-radical initiator for processing of rubber and polymers. It is well-known as a thermally stable material and its controlled decomposition in high temperatures, making it a good choice for manufacturing processes that require high temperatures.

The compound is symmetrical in its peroxide structure which allows for efficient generation of radicals during heating. This feature lets Dicumyl Peroxide to improve mechanical durability, heat resistance and durability of finished materials.

Because of its reliable performance, Dicumyl Peroxide is commonly used in plastics, elastomers, and specialty polymer formulations that require consistent crosslinking and long-term stability.


Application of Dicumyl Peroxide

Polymer Crosslinking Applications

Dicumyl Peroxide is extensively used as a crosslinking agent in thermoplastics and elastomers. It helps improve tensile strength, thermal resistance, and dimensional stability of finished products.

These applications are closely associated with requirements in polymers, where controlled crosslinking defines final material performance.

Rubber Vulcanization & Elastomer Processing

In rubber processing, Dicumyl Peroxide is used as a peroxide curing agent, offering an alternative to sulfur-based systems. It provides uniform curing and improved aging resistance in rubber compounds.

These uses align with the needs of rubber industries, where consistent curing and durability are critical.

Free-Radical Initiator Systems

Dicumyl Peroxide acts as a free-radical initiator in polymerization reactions. It supports controlled polymer growth and crosslink formation in high-temperature environments.

In such systems, it may be used alongside peroxides such as Di-Tert-Butyl Peroxide or initiators like Tert-Butyl Peroxybenzoate to fine-tune reaction behavior.

Co-Agent & Specialty Crosslinking Systems

In advanced formulations, Dicumyl Peroxide is used with co-agents such as Triallyl Isocyanurate to enhance crosslink efficiency and improve mechanical properties in high-performance polymer systems.
