This chemical is primarily utilized as a flame retardant in various polymer systems, including polyolefins, polyesters, and polyamides. Its spirocyclic structure enhances thermal stability, making it effective in reducing flammability and improving fire resistance in materials. It is often incorporated into plastics, textiles, and coatings to meet safety standards in industries such as automotive, construction, and electronics. Additionally, its compatibility with other additives allows for versatile application without significantly compromising the mechanical properties of the host material.
