For professionals in the chemical and materials science industries, a deep understanding of product specifications is fundamental to successful application and procurement. Diphenyl Isodecyl Phosphate (DPDP), identified by CAS number 29761-21-5, is a sophisticated chemical compound valued for its performance as a flame retardant and plasticizer. NINGBO INNO PHARMCHEM CO.,LTD. prides itself on providing transparent and detailed information about our DPDP product to support our B2B clients in their decision-making processes.

The chemical identity of DPDP is confirmed by its molecular formula C22H31O4P and a molecular weight of 390.45. These fundamental characteristics dictate its behavior and efficacy in various applications. As a leading manufacturer and supplier, we ensure our DPDP meets high purity standards, with an assay of 99% minimum. This high purity is critical for achieving the desired flame retardant properties and consistent plasticizing effects in your formulations.

Key typical properties of our Diphenyl Isodecyl Phosphate include:

• Appearance: Clear liquid. This visual characteristic simplifies handling and quality control during its integration into manufacturing processes.
• Phosphorus Content (P%): Typically around 7.9%. The phosphorus content is a direct indicator of the compound's potential as a flame retardant, as phosphorus-based compounds are known for their efficacy in inhibiting combustion.
• Specific Gravity @ 25℃: Ranging from 1.070 to 1.080 g/cm³. This density value is important for calculating dosages and understanding its behavior in mixtures.
• Viscosity @ 25℃: Within the range of 25 to 30 cps. A moderate viscosity ensures ease of pumping, mixing, and application, contributing to efficient processing.
• Acidity (mg KOH/g): A maximum of 0.1. Low acidity is crucial as high acidity can lead to corrosion or degradation of processing equipment and the final product.
• Flash Point: A minimum of 240℃. A high flash point indicates low volatility and reduced flammability of the product itself, enhancing safety during storage and handling.

These technical specifications highlight why DPDP is an excellent choice for demanding applications requiring enhanced safety and performance. Its effectiveness as a self-extinguishing flame retardant and plasticizer, combined with its economic benefits and low volatility, makes it a superior additive for various polymers, including PVC, PC, and acrylic resins.
