Description

tert-Butyl Peroxycinnamate is a high-purity organic peroxide widely utilized as a polymerization initiator and crosslinking agent. Its controlled decomposition properties are critical for initiating free-radical reactions in the production of specialty polymers and resins. This compound is essential for manufacturers in the plastics, coatings, and adhesive industries seeking to optimize reaction kinetics and final product performance.

Application

• Primary initiator for the polymerization of styrene, acrylates, and vinyl monomers.
• Crosslinking agent for unsaturated polyester resins in fiberglass-reinforced plastics (FRP) and sheet molding compounds (SMC).
• Key component in the production of thermoset coatings and adhesives requiring controlled cure profiles.
• Used in the synthesis of specialty polymers where specific molecular weight and branching are required.
• Employed in curing systems for elastomers and rubber compounds.
• Acts as a reactive intermediate in fine chemical and pharmaceutical synthesis.

Quality Control

Our tert-Butyl Peroxycinnamate is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay and impurity profiling, 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. Keep away from reducing agents, strong acids, bases, and other incompatible materials. Due to its nature as an organic peroxide, store at recommended temperatures and monitor shelf life. Always refer to the Safety Data Sheet (SDS) for specific handling and storage instructions.
