Flame Retardant EcoFlame B-463 Tetrabromophthalic Anhydride(RB-49/PHT4) for unsaturated polyester

EcoFlame B-463 Tetrabromophthalic Anhydride is a highly efficient brominated flame retardant widely applied in polymer materials for enhanced fire safety. With outstanding thermal stability and excellent compatibility, it serves as a key additive across various plastic and resin systems, providing reliable and long-lasting flame retardancy.

As a reactive flame retardant, it is especially suitable for polyesters, unsaturated polyesters, and epoxy resins. It chemically incorporates into the polymer matrix, ensuring permanent flame resistance without leaching or degrading material properties. This makes it ideal for high-performance applications such as electronic circuit boards, composite materials, and insulating coatings.

As an additive flame retardant, EcoFlame B-463 can be effectively used in polystyrene, polypropylene, and ABS resins. It is often synergized with antimony trioxide to enhance flame retardant efficiency, making it suitable for a wide range of engineering plastics and synthetic compounds. This flexibility allows it to be used in injection molding, extrusion, and other thermoplastic processes.

Its major advantages include high bromine content, excellent thermal stability, low impact on physical properties of substrates, and compliance with international safety standards. It is widely used across electronics, automotive, construction, and transportation industries where stringent flame retardant requirements must be met.

Available as a fine white powder, this product is packaged in 25 kg woven bags with inner polyethylene lining. Quality assurance and batch consistency are guaranteed, making it a reliable choice for industrial and commercial applications worldwide.
