Description

1,3-Isobenzofurandione, 3A,4,7,7A-Tetrahydro-, Polymer With 1,2-Ethanediol And 2,5-Furandione, Brominated is a specialized brominated polymeric resin derived from tetrahydrophthalic anhydride, ethylene glycol, and maleic anhydride. This engineered material is valued for its inherent flame-retardant properties imparted by bromination, making it a critical component in formulations requiring enhanced fire safety. It is primarily utilized by manufacturers in the polymer and coatings industries seeking to improve the fire resistance of their end products while maintaining material integrity.

Application

• As a reactive flame-retardant additive or co-monomer in unsaturated polyester resins (UPR) for composites.
• Formulation of fire-retardant coatings, paints, and varnishes for construction materials and electronics.
• Component in specialty adhesives and sealants where flame retardancy is a regulatory or safety requirement.
• Use in the production of flame-retardant gel coats and laminates for marine and transportation applications.
• Potential modifier for epoxy resin systems to impart brominated fire resistance.
• Research and development of advanced polymeric materials with specific thermal and fire safety profiles.
