Description

tert-Butyl Isopropylphenyl Peroxide is a high-purity organic peroxide widely recognized for its role as a polymerization initiator and crosslinking agent. Its controlled decomposition kinetics make it a critical component for achieving specific polymer properties and reaction rates in industrial processes. This compound is essential for manufacturers in the polymer, rubber, and specialty chemical industries seeking reliable and efficient free-radical sources.

Application

• Primary initiator for the polymerization of styrene, ethylene, and other vinyl monomers.
• Key component in the production of expandable polystyrene (EPS) and other styrenic polymers.
• Used as a crosslinking agent for unsaturated polyesters and elastomers in composite materials.
• Employed in the curing of thermoset resins for coatings, adhesives, and fiber-reinforced plastics.
• Facilitates controlled degradation and modification of polyolefins to improve processability.
• Serves as an intermediate in organic synthesis for introducing peroxide functionalities.

Quality Control

Our tert-Butyl Isopropylphenyl Peroxide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets precise specifications for polymerization-grade materials. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to guarantee batch-to-batch consistency and performance reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Due to its nature as a strong oxidizer, it must be segregated from reducing agents, acids, bases, and combustible materials. Recommended storage temperature is 15-25°C. Do not store for prolonged periods; monitor container integrity regularly.
