polyphosphazenes_1
polymerPolyphosphazenes 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.

Safety & Biocompatibility
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
