Description

Bis(2,3-Dibromopropyl) Chlorophosphate is a halogenated organophosphorus compound that serves as a highly effective flame retardant additive. Its primary value lies in its ability to impart significant fire resistance to polymeric materials by interrupting the combustion cycle. This product is essential for manufacturers in the plastics, textiles, and electronics industries seeking to meet stringent fire safety regulations for their products.

Application

• As a reactive or additive flame retardant in polyurethane foams (flexible and rigid).
• Enhancing the fire resistance of unsaturated polyester resins and epoxy resins.
• Application in flame-retardant coatings and adhesives for various substrates.
• Use in textile back-coatings and treatments to reduce fabric flammability.
• Formulation of flame-retardant compounds for wire and cable insulation.
• Potential use as an intermediate for synthesizing other specialized flame-retardant chemicals.
