Primarily used as a flame retardant, it is incorporated into materials like plastics, textiles, and coatings to reduce flammability and slow the spread of fire. It is particularly effective in applications requiring high thermal stability, such as in electrical and electronic equipment, where it helps prevent fire hazards. Additionally, it is utilized in the production of fire-resistant foams and insulation materials. However, its use is increasingly regulated due to environmental and health concerns, leading to a shift toward safer alternatives in many industries.
