Description

1,2,5,6,9,10-Hexabromocyclododecane is a high-purity brominated flame retardant additive, specifically a stereoisomer of hexabromocyclododecane (HBCD). This compound is valued for its exceptional efficacy in imparting fire resistance to a wide range of polymeric materials. It is primarily utilized by manufacturers in the construction, electronics, and textile industries seeking to meet stringent fire safety standards. Our supply is characterized by consistent quality and reliable performance in demanding applications.

Application

• As a flame retardant additive for expanded (EPS) and extruded (XPS) polystyrene foam insulation used in building and construction.
• Imparting fire resistance to high-impact polystyrene (HIPS) and other thermoplastic polymers for electronic enclosures and components.
• Flame retardant treatment for textile back-coatings, particularly for upholstery fabrics and technical textiles.
• Enhancing the fire safety profile of adhesives, sealants, and coatings where halogenated systems are specified.
• Used in the formulation of specialty polymer compounds requiring high thermal stability and flame retardancy.
