Description

1,3,5-Tris[2-[(Dihydroxyphosphino)Oxy]Ethyl]-1,3,5-Triazine-2,4,6(1H,3H,5H)-Trione is a multifunctional organophosphorus compound that serves as a highly effective flame retardant and cross-linking agent. Its molecular structure, featuring multiple reactive phosphonate and isocyanurate groups, provides exceptional thermal stability and char-forming properties. This chemical is essential for manufacturers in the polymer, textile, and coatings industries seeking to enhance the fire resistance and durability of their materials while maintaining performance.

Application

• Flame Retardant for Polymers: A key additive in polyurethane foams, epoxy resins, polyesters, and polyamides to meet stringent fire safety standards (e.g., UL 94, LOI).
• Textile Finishing Agent: Imparts durable flame-retardant properties to fabrics, including cotton, polyester blends, and technical textiles for protective clothing and furnishings.
• Reactive Cross-Linker: Used in thermosetting resin systems to improve thermal stability, mechanical strength, and chemical resistance of the final cured product.
• Intumescent Coating Formulations: Acts as a carbonific and acid source in coatings that expand to form an insulating char layer when exposed to fire.
• Adhesive and Sealant Modifier: Enhances the fire performance and heat resistance of high-performance adhesives and sealants used in construction and automotive applications.
• Paper and Wood Treatment: Applied to improve the flame retardancy of paper products, wood composites, and cellulose-based materials.
