polyphosphazenes_2
polymerPolyphosphazenes are a class of inorganic-organic hybrid polymers with a backbone of alternating phosphorus and nitrogen atoms, whose properties can be tailored through various organic side-group substitutions. These materials are valued in aerospace, biomedical, and specialty elastomer applications for their thermal stability, flame resistance, and chemical inertness; they offer advantages over conventional organic polymers where thermal performance and low flammability are critical. The material family continues to be refined in research settings for emerging applications requiring combined mechanical performance and environmental durability.

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.
