| Electronics & Electrical | Used in flame-retardant materials for electronic device housings, circuit boards, and similar components | Combined with other formulation components during injection molding or lamination to enhance product fire performance |
| Construction Materials | Applied as a flame retardant in construction products such as plastic profiles and insulation materials | Added as an additive to resins or other base materials during construction material production to improve flame retardancy |
| Automotive Industry | Used for flame-retardant treatment of automotive interior parts, wire harness jackets, and similar components | Incorporated into plastic or rubber materials during automotive component manufacturing to meet vehicle safety standards |
Manufacturing Quality Control of Bisphenol-A bis(diphenyl phosphate)
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Main Component Content (Purity) | High-Performance Liquid Chromatography (HPLC) | A reverse-phase C18 chromatographic column and a UV detector (usually detecting at 254 nm or 280 nm wavelength) are used. The main peak area of BDP is determined by external standard method or area normalization method to calculate its purity. |
| Impurity Analysis (e.g., Monophosphate Esters, Free Phenols, etc.) | High-Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) | Impurities are separated by HPLC and identified and quantified using mass spectrometry. It can detect structural analogs such as mono(di-phenyl phosphate ester), bisphenol A, and phosphorus ester byproducts. |
| Moisture Content | Karl Fischer Titration | The moisture content in the sample is titrated using volumetric or coulometric Karl Fischer reagent, suitable for heat-sensitive or low-water-content organophosphorus flame retardants. |
| Ash/Inorganic Residue | High-Temperature Calcination Method (Muffle Furnace Method) | The sample is calcined at high temperature (typically 600–800°C) until constant weight is achieved, and the residual inorganic matter is measured to evaluate the level of inorganic impurities or catalyst residues. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | The sample is heated at a controlled rate under an inert or air atmosphere, and the mass loss curve is recorded to assess the decomposition temperature and thermal stability of BDP. |
| Elemental Composition (Phosphorus Content) | Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) or Elemental Analyzer | The phosphorus content is determined after sample digestion to verify whether it matches the theoretical value (BDP theoretical P content is approximately 9.2%), used for quality consistency control. |
| Appearance and Color | Visual Color Comparison or Colorimeter | The color of the sample (usually white to pale yellow powder or granules) is observed. When necessary, standard color cards or instruments are used to quantify color to judge oxidation or degradation levels. |
| Melting Point | Melting Point Apparatus (Capillary Method or DSC) | The melting temperature range (typical melting point of BDP is approximately 130–140°C) is determined using differential scanning calorimetry (DSC) or traditional capillary method as an auxiliary indicator of purity. |
