ABSTRACT:
A multiple layer article of a thermoformable structural polymeric layer which is susceptible to damage upon exposure to hydrohalocarbon blowing agents and a polymeric layer which is a barrier to such hydrohalocarbon blowing agents provides a useful refrigerator liner. Related structures are useful for preventing the migration of hydrohalocarbons.
