STABILIZED COMPOSITION CONTAINING HYDROFLUOROALKANE, PREMIX FOR PRODUCTION OF POLYMER FOAM AND POLYMER FOAM OBTAINED THEREFROM

摘要

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