Used as a reactive flame retardant in polyurethane foams, particularly flexible and rigid foams for furniture, bedding, and automotive interiors. It becomes part of the polymer matrix during curing, providing durable flame resistance without leaching out. Also employed in coatings and adhesives where thermal stability and fire safety are required. Its hydroxyl groups allow it to act as a crosslinking agent, enhancing mechanical strength and heat resistance in the final product. Common in construction materials and electronics encapsulation for improved fire performance.
