Used as a flame retardant in plastics, rubber, and textiles due to its ability to release water and form a protective glassy layer when exposed to heat. It acts synergistically with other flame retardants like antimony trioxide and aluminum hydroxide, enhancing fire resistance. Commonly added to wire and cable compounds, construction materials, and electronic enclosures. Also serves as a smoke suppressant and helps improve thermal stability during processing. In wood composites, it provides protection against fungal decay and fire. Its low solubility in water makes it suitable for applications requiring moisture resistance.
