Description

γ-Hexabromocyclododecane is a specific stereoisomer of hexabromocyclododecane (HBCD), a brominated flame retardant. This compound is valued for its high efficiency in suppressing combustion in various polymer matrices. It is primarily required by manufacturers in the construction, textile, and electronics industries for producing flame-retardant expanded polystyrene (EPS) and extruded polystyrene (XPS) foam insulation boards, as well as high-impact polystyrene (HIPS) for electrical enclosures.

Application

• Flame retardant for expanded polystyrene (EPS) foam used in building and construction insulation.
• Flame retardant for extruded polystyrene (XPS) foam in insulation panels and boards.
• Flame retardant additive in high-impact polystyrene (HIPS) for electronic equipment housings.
• Flame retardant treatment for textiles and upholstery back-coatings.
• Component in polymer formulations requiring enhanced fire safety standards.
• Used in the production of flame-retardant adhesives and coatings.
