It has been proven that colloidal systems with particle sizes of no more than 50 nm, containing components of both gas-phase and solid-phase action, are the most effective. The principles for the development of synthetic inorganic flame retardants for fine-fiber polymeric materials are formulated.</p><p><i>Application field of research.</i> The results obtained are the basis for the targeted synthesis of new non-toxic flame retardants for fine-fiber polyester materials for various purposes including building insulation and sound insulator.</p> ER -
