Description

1,3-Isobenzofurandione, 3A,4,7,7A-Tetrahydro-, Polymer With 2,2-Bis(Bromomethyl)-1,3-Propanediol, 1,2-Ethanediol And 2,5-Furandione, Brominated is a specialized brominated polymeric flame retardant engineered for demanding applications. This compound is valued for its ability to impart significant fire resistance while maintaining compatibility with various polymer matrices. It is primarily sought by manufacturers in the plastics, electronics, and construction materials industries requiring high-performance, halogen-based flame retardant additives.

Application

• As a reactive or additive flame retardant for engineering thermoplastics like polyamides (nylon) and polyesters (PBT, PET).
• Enhancing fire safety in thermoset resins used for printed circuit boards (PCBs) and electrical encapsulants.
• Formulation of fire-resistant coatings and adhesives for construction and automotive applications.
• Manufacture of fire-retardant polyurethane foams for insulation and cushioning.
• Production of wire and cable jacketing to meet stringent fire safety standards (e.g., UL, IEC).
• Use in synthetic fibers and textiles to create flame-retardant fabrics.
