Plastaform

Plastaform was a type of material used by the Romulans in the interior construction of their Birds-of-Prey.

In an attempt to deceive the crew of the USS Enterprise (NCC-1701) in 2266, the commander of the Praetor's flagship jettisoned all debris from his ship, including metal molds, conduit, plastaforms, and the corpse of a centurion who had died in the attack.
