Description

Acetyl Peroxide is a highly reactive organic peroxide compound, primarily utilized as a radical initiator in polymerization reactions. Its effectiveness in generating free radicals under controlled conditions makes it a critical component for producing polymers with specific molecular weights and properties. This compound is essential for manufacturers in the plastics, resins, and specialty chemical synthesis industries seeking efficient and reliable initiation for their processes. Acetyl Peroxide CAS NO 110-22-5 is handled under strict safety protocols due to its reactive nature.

Application

• Polymerization Initiator: A key free-radical source for the production of polyethylene, polystyrene, polyvinyl chloride (PVC), and other polymers.
• Cross-linking Agent: Used in the curing and cross-linking of unsaturated polyester resins and elastomers to enhance material strength and thermal stability.
• Chemical Synthesis Intermediate: Employed in organic synthesis to facilitate oxidation reactions and the introduction of peroxide functional groups.
• Resin Manufacturing: Acts as a catalyst or hardener in the production of fiberglass-reinforced plastics and composite materials.
• Adhesive & Coating Formulations: Incorporated into formulations where controlled curing at ambient or elevated temperatures is required.
• Textile & Paper Processing: Used in bleaching and modification processes for fibers and pulp.

Quality Control

Our Acetyl Peroxide is manufactured and tested under stringent quality management systems to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) detailing purity, assay, and critical impurity profiles. Our quality protocols are designed to meet the demanding requirements of industrial polymerization and chemical synthesis. Specifications can be aligned with customer-specific needs upon request.

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 properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) and keep quantities minimal. Isolate from incompatible materials such as reducing agents, strong acids, heavy metal compounds, and amines. Refer to the Safety Data Sheet (SDS) for complete handling and storage instructions.
