Description

2,2'-[[2-[[[5,5-bis(bromomethyl)-1,3,2-dioxaphosphorinan-2-yl]oxy]methyl]-2-ethylpropane-1,3-diyl]bis(oxy)]bis[5,5-bis(bromomethyl)-1,3,2-dioxaphosphorinane] P,2,2'-trioxide is a highly brominated phosphorus-based compound designed as a reactive flame retardant additive. It matters for formulators seeking to enhance the fire resistance of polymers while maintaining processing stability and material properties. This product is primarily needed by manufacturers in the plastics, coatings, and specialty chemical industries for creating flame-retardant polyurethanes, epoxies, and other thermoset resins.

Application

• Reactive Flame Retardant for Polyurethane Foams: Incorporated into rigid and flexible foam formulations for construction, automotive, and furniture applications.
• Flame Retardant for Epoxy Resins: Used in electronic encapsulants, printed circuit board laminates, and composite materials.
• Additive for Unsaturated Polyesters: Enhances fire safety in fiberglass-reinforced plastics (FRP) for marine and transportation sectors.
• Component in Intumescent Coatings: Acts as a char-forming agent in fire-protective paints and coatings for structural steel.
• Specialty Chemical Intermediate: Serves as a building block for synthesizing more complex phosphorus-bromine synergistic flame retardants.
• Cable & Wire Insulation: Imparts flame retardancy to polymer jacketing and insulation materials.
