Understanding the chemical intricacies of flame retardants is key to unlocking their full potential in material science. At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing comprehensive information about our products, including the highly effective Flame Retardant DOPO (CAS 35948-25-5). This document aims to elucidate its chemical properties, specifications, and the diverse applications where it significantly enhances material safety.

Flame Retardant DOPO, chemically known as 9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-oxide, is a phosphorus-containing organic compound. Its molecular formula is C12H9PO2, and it typically presents as a white crystalline powder or flake. A critical aspect of its chemical profile is its high purity, commonly exceeding 99.5%. This level of purity ensures consistent performance and reliability in demanding applications. For manufacturers looking to buy flame retardant DOPO, this high purity is a key indicator of quality and efficacy.

The solubility characteristics of DOPO are noteworthy. It is easily soluble in polar organic solvents such as methanol and ethanol, and also in chlorinated solvents like chloroform. It exhibits solubility in aromatic solvents such as benzene and toluene, but is largely insoluble in water. This solubility profile dictates its suitability for various processing methods and polymer matrices. Understanding these chemical properties is vital when considering its use as either a reactive or additive flame retardant.

Key specifications for Flame Retardant DOPO often include parameters like melting point, typically in the range of 116-120°C, and a maximum limit for unwanted byproducts like OPP (often below 0.1%). These specifications underscore its high quality and consistent performance. The presence of a phosphorus-carbon bond is a defining feature, which contributes significantly to its superior flame retardant efficiency compared to many standard phosphate ester flame retardants. This chemical advantage is a primary reason for its adoption in advanced halogen-free flame retardant applications.

The applications for Flame Retardant DOPO are extensive, reflecting its versatility and effectiveness. It is widely used in polymer materials to enhance their fire resistance. Specific applications include its incorporation into epoxy resins for printed circuit boards (PCBs), electronic plastics, linear polyesters, polyamides, and polyurethanes. In these materials, DOPO acts as both a reactive and additive flame retardant, providing robust protection against ignition and flame propagation. Manufacturers interested in the flame retardant DOPO price will find that its enhanced performance and safety benefits justify the investment.
