Description

2,2,4,4,6,6-Hexabromo-2,2,4,4,6,6-Hexahydro-1,2,3,4,5,6-Triazatriphosphorine is a high-bromine content heterocyclic organophosphorus compound, serving as a highly effective flame retardant and smoke suppressant. Its value lies in its ability to impart significant fire resistance to polymers while maintaining thermal stability and compatibility with various resin systems. This product is essential for manufacturers in the plastics, electronics, and construction materials industries seeking to meet stringent fire safety regulations.

Application

• As a reactive or additive flame retardant in engineering thermoplastics such as polyamides (nylon), polyesters (PBT, PET), and polycarbonates.
• Enhancing the fire resistance of epoxy resin systems used in printed circuit boards (PCBs), electrical encapsulants, and composite materials.
• Formulation of fire-retardant polyurethane foams for insulation, automotive interiors, and furniture.
• Improving the flame retardancy of synthetic fibers and textiles for protective clothing and upholstery.
• Use in intumescent coating systems to provide passive fire protection for structural steel and other materials.
• As a key component in halogenated flame retardant blends for wire and cable jacketing.
