polyphosphazenes_1

Polyphosphazenes are a synthetic polymer family built on a phosphorus-nitrogen backbone, offering tunable properties through organic side-chain substitution. They are valued in specialized applications requiring flame resistance, chemical stability, and low flammability, particularly in aerospace, defense, and biomedical sectors where conventional polymers fall short. Their molecular flexibility allows engineers to customize stiffness, thermal behavior, and biocompatibility, making them especially relevant for high-performance elastomers, protective coatings, and medical devices.
