Applications of 838-85-7
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Flame retardant and reactive flame retardant additive in polycarbonate production | Participates in interfacial or melt polycondensation with bisphenol A and phosgene (or diphenyl carbonate) during melt compounding or polymerization; diphenyl phosphate serves as a chain terminator or comonomer to incorporate phosphate structures and impart flame retardancy |
| Electrical & Electronics | Flame retardant modifier for engineering plastics such as PC/ABS | Melt-compounded with resin matrices (e.g., polycarbonate, acrylonitrile-butadiene-styrene copolymer) using a twin-screw extruder to achieve uniform dispersion and meet UL94 V-0 flame retardancy requirements |
| Coatings Industry | Phosphorus-containing flame retardant additive and char-forming promoter in coatings | Used synergistically with other flame retardants (e.g., melamine derivatives) in acrylic or epoxy resin coating systems to catalyze dehydration and char formation at elevated temperatures, yielding a dense, protective char layer |
| Textile Printing & Dyeing | Post-treatment flame retardant for synthetic fibers such as polyester and nylon | Applied via padding-drying-curing process; diphenyl phosphate is formulated with nitrogen-containing synergists (e.g., urea, melamine) and thermally cured at 150–180 °C to impart flame retardancy to fiber surfaces |
| Lubricating Oil Additives | Anti-wear and antioxidant additive component | Formulated with other phosphorus- or sulfur-containing additives (e.g., ZDDP) and incorporated into mineral or synthetic hydrocarbon base oils to form a protective phosphate film on metal surfaces, reducing friction and wear |
