Kunststoffschaum mit Formgedächtnis.

摘要

A shape memory polymer foam which takes on a deformed shape and an as-molded shape, said deformed shape being produced when the polymer foam is compressed at a temperature higher than the glass transition point (Tg) of the polymer and then kept compressed at a temperature lower than the Tg until compression sets, said as-molded shape being produced when the compressed polymer foam is heated again to a temperature higher than the Tg until it recovers its original shape.
