Description

Tetrabromobisphenol A Bis(Dibromopropyl Ether) is a high-performance brominated flame retardant additive. This compound is valued for its excellent thermal stability and effectiveness in enhancing the fire resistance of various polymer matrices. It is primarily needed by 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 polyolefins such as polypropylene (PP) and polyethylene (PE).
• Enhancing fire resistance in engineering thermoplastics like ABS, HIPS, and PBT for electronic housings and components.
• Flame retardant treatment for textiles and fabrics used in protective clothing, upholstery, and curtains.
• Application in epoxy resin systems for printed circuit boards (PCBs) and electrical laminates.
• Use in polyurethane foams (rigid and flexible) for construction and automotive insulation.
• Formulation of wire and cable coatings to meet safety standards like UL 94 and IEC 60332.
• Flame retardant additive for adhesives, sealants, and coatings.
