Description

Hexabromocyclododecane (HBCD) is a brominated flame retardant widely recognized for its high efficacy in inhibiting the spread of fire in various polymer systems. Its primary commercial value lies in providing critical fire safety to insulation materials, particularly expanded and extruded polystyrene foams used in the construction industry. This compound is essential for manufacturers seeking to meet stringent international fire safety standards and building codes for energy-efficient structures.

Application

• Polystyrene Foam Insulation: The dominant application, providing flame retardancy to both Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS) foams used in building and construction for walls, roofs, and foundations.
• High-Impact Polystyrene (HIPS): Used in the production of flame-retardant HIPS for applications in electrical and electronic equipment housings.
• Textile Back Coatings: Imparts flame resistance to textiles, including upholstery fabrics, curtains, and other interior furnishings.
• Adhesives and Sealants: Incorporated into formulations where enhanced fire performance is required without significantly compromising other physical properties.
• Polypropylene and Polyethylene: Used as an additive flame retardant in certain polyolefin applications, though less common than in polystyrene.
