    Phosphate Esters

    Phosphate ester plasticizers as co-flame retardant can significantly improve the burning and smoke behavior for flexible products. In flame-retardant formulations, phosphate esters act through several mechanisms: Firstly, they can undergo thermal degradation at elevated temperatures, releasing phosphoric acid that forms a protective char layer on the material's surface. This char layer acts as a barrier, shielding the underlying material from heat and oxygen, thus inhibiting further combustion. Additionally, phosphate esters can interact with free radicals and reactive intermediates generated during the combustion process, interrupting the chain reaction and reducing the overall flammability of the material. Moreover, phosphate esters exhibit synergistic effects when combined with other flame retardants, enhancing their efficiency and broadening the spectrum of materials that can be effectively protected against fire. This versatility makes phosphate esters indispensable in various industries, including adhesives and sealants for the applications constructive sealants, automotive adhesives, textile bonding and foam adhesives, where fire safety is a critical concern. They can assist in the general trend towards reducing / eliminating antimonium trioxide and chlorinated paraffins.
