Description

Bis(1-Oxoisononyl) Peroxide is a high-purity organic peroxide compound, widely recognized for its role as an efficient initiator in polymerization reactions. Its primary commercial value lies in its ability to provide controlled decomposition rates, which is critical for achieving specific polymer properties and ensuring process safety. This product is essential for manufacturers in the polymer and plastics industries, particularly for the production of specialty resins, elastomers, and other high-performance materials where precise molecular weight control is required.

Application

• Primary initiator for free-radical polymerization of vinyl monomers such as styrene, vinyl chloride, and acrylates.
• Used in the production of polyethylene (LDPE) and other polyolefins.
• Cross-linking agent for silicone rubbers and certain thermoset polymers.
• Key component in the synthesis of acrylic resins and specialty adhesives.
• Employed in the manufacture of unsaturated polyester resins (UPR) for composites.
• Facilitates controlled curing processes in fiberglass reinforced plastics (FRP).

Quality Control

Our Bis(1-Oxoisononyl) Peroxide is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including purity assay and active oxygen content determination, to meet exacting industry standards. Certificates of Analysis (COA) documenting all 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 incompatible materials such as reducing agents, strong acids, and bases. Due to its nature as a strong oxidizer, store separately in a dedicated, temperature-controlled environment (recommended 15-25°C).
