Description

Tetrabromodipentaerythritol is a high-performance brominated flame retardant additive. This compound is valued for its excellent thermal stability and high bromine content, which provides superior flame-retardant efficiency in polymer systems. It is primarily used by manufacturers in the plastics, textiles, and construction materials industries seeking to enhance the fire safety of their products while maintaining material properties.

Application

• As a reactive or additive flame retardant in unsaturated polyester resins (UPR) for construction panels and automotive parts.
• Incorporation into epoxy resin systems for printed circuit boards (PCBs) and electronic encapsulants.
• Flame retardant treatment for polyurethane (PU) foams used in insulation and furniture.
• Additive in acrylonitrile butadiene styrene (ABS), high-impact polystyrene (HIPS), and other engineering thermoplastics.
• Component in intumescent fire-retardant coatings and paints for structural steel and wood.
• Use in textile back-coatings and treatments for curtains, upholstery, and protective clothing.
• Application in wire and cable insulation compounds to meet stringent fire safety standards.
