Hexabromobenzene is primarily used as a flame retardant in various industrial applications. It is incorporated into materials such as plastics, textiles, and electronic components to reduce their flammability and enhance fire safety. The compound is particularly effective in high-temperature environments, making it suitable for use in electrical and electronic equipment where heat resistance is critical. Additionally, it has been utilized in the production of adhesives and coatings to improve their fire-retardant properties. However, due to environmental and health concerns, its use has become more regulated, and alternative flame retardants are increasingly being explored.
