Description

Perkadox Pf-Dbm25 CAS NO 1931-62-0 is a high-purity, dialkyl peroxide-based organic peroxide primarily used as a polymerization initiator and crosslinking agent. This compound is critical for initiating free-radical reactions in polymer synthesis, offering controlled decomposition rates for consistent and reliable results. It is essential for manufacturers in the plastics, rubber, and specialty polymer industries requiring precise initiation for high-quality polymer production.

Application

• Polymerization Initiator: Used for the production of polyethylene (LDPE), polystyrene, and polyvinyl chloride (PVC).
• Crosslinking Agent: Essential for the crosslinking of unsaturated polyester resins and silicone rubbers to enhance thermal and mechanical properties.
• Curing Agent: Employed in the curing of fiberglass-reinforced plastics (FRP) and composite materials.
• Synthesis Intermediate: Serves as a key intermediate in organic synthesis for introducing peroxide functionalities.
• Rubber Vulcanization: Acts as a free-radical vulcanizing agent for ethylene-propylene-diene monomer (EPDM) and other elastomers.
• Modifier for Polymer Properties: Used to control molecular weight and branching in polymer chains during manufacture.

Quality Control

Our Perkadox Pf-Dbm25 is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. The product undergoes comprehensive analytical testing, including assay by HPLC and impurity profiling, to meet exacting industry specifications. A Certificate of Analysis (COA) detailing purity, active oxygen content, and other critical parameters is provided with each shipment to support your quality assurance protocols.

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 an organic peroxide and being easily oxidized, it is recommended to store under an inert atmosphere where practical and keep separated from incompatible materials such as strong acids, reducing agents, and heavy metal compounds. Recommended storage temperature is 15-25°C.
