The Polymold.
Polymold was a versatile substance manufactured by Plas-Tech.
History[]
Among its various abilities, it was a crucial component in Derek Powers' synthetic skin. Near the end of his career, when legal channels of procurement were failing him, Powers (as Blight) attempted to steal a cartload of Polymold canisters from a Plas-Tech warehouse, but was thwarted by Batman.
While useful, Polymold was also flammable, as Blight demonstrated while covering his escape.
