Polyduranium is a material used by several states and races, mainly for defense.

In 2153, polyduranium was encountered by Enterprise in the doors of a Delphic Expanse sphere and in the hull of an Osaarian ship. (ENT episode: "Anomaly")

The hull plating of the USS Defiant included a mix of polyduranium, kelindide, rodinium and toranium. (ST reference: Star Trek: Deep Space Nine Technical Manual)

Polyduranium was also used in a bulkhead on the bridge of the Defiant. In 2371, Ornithar expressed an interest in it but he believed it had no real value. (DS9 episode: "The Search")

Polyduranium is also used in the casing of Klingon bat'leths. (ST reference: Star Trek: Deep Space Nine Technical Manual)
