Stabilized compositions comprising hydrofluoroalkanes, premixtures intended for the preparation of polymeric foams and polymeric foams obtained by the use thereof

摘要

Compositions comprising at least one hydrofluoroalkane and at least one stabilizing agent chosen from quinones and compounds containing a nitroso group, added in an amount sufficient to stabilize the hydrofluoroalkanes. These compositions can especially be used in premixtures for polyurethane foams.
