Application

This fluorinated phosphate ester serves as a high-performance flame retardant in lithium-ion battery electrolytes, where it suppresses thermal runaway by forming protective char layers. Its application extends to specialty polymers and coatings requiring UL94 V-0 compliance without compromising dielectric properties. Researchers also employ it as a fluorine-rich precursor for synthesizing advanced flame-retardant additives with reduced environmental persistence compared to brominated alternatives.
