Description

Dihydro-3-[(6-Oxide-6H-Dibenz[C,E][1,2]Oxaphosphorin-6-Yl)Methyl]-2,5-Furandi-One is a specialized organophosphorus compound that functions as a highly effective reactive flame retardant. Its molecular structure allows it to be chemically incorporated into polymer chains, providing durable flame resistance without compromising the mechanical properties of the final material. This product is essential for manufacturers in the plastics, resins, and synthetic fiber industries seeking to enhance the fire safety of their high-performance materials.

Application

• Reactive Flame Retardant for Engineering Plastics: Chemically bonds into polymers like polyamides (PA), polyesters (PBT, PET), and epoxy resins to provide permanent, non-blooming flame retardancy.
• Thermoset Resin Modifier: Used in the formulation of flame-retardant epoxy resins for printed circuit boards (PCBs), electrical encapsulants, and composite materials.
• Synthetic Fiber Additive: Incorporated during the polymerization process of fibers such as polyester to produce inherently flame-retardant textiles for protective clothing and home furnishings.
• Polyurethane Foam Applications: Serves as an additive in rigid and flexible polyurethane foams for construction and automotive interiors to meet stringent fire safety standards.
• High-Performance Coating Systems: Enhances the fire resistance of intumescent and other protective coatings for structural steel, cables, and other substrates.
