Polyamide‐borax composites were prepared from solution of polyimide and the borax using N ‐methyl‐2‐pyrrolidone as a solvent. The Polyimide‐borax composites films (PI‐BX) characterized by FTIR, SEM and x‐ray. The borax content significantly influences thermal behavior of the polymeric films, such as glass transition and decomposition temperatures of polyimide‐borax composites. The glass transition temperatures of the composites were higher than that of the original polyimide. The flammability properties of them were demonstrated by cone calorimeter and indicate that the borax composites have significantly decreased in heat release rate, and mass loss rate. The PI‐BX composites appears very good the flame retardant properties.
