Used primarily as a flame retardant in various polymer systems, including polyurethane foams, adhesives, and coatings. It enhances fire resistance by releasing chlorine radicals that interrupt the combustion process. Additionally, it is employed in the production of flexible and rigid foam products, particularly in the construction and automotive industries, to meet fire safety standards. Its compatibility with other additives and its effectiveness at relatively low concentrations make it a practical choice for improving material safety.
