description The invention relates to advantageous blowing agent mixtures comprising HFC-365mfc and HFC-227 in addition to 1,1,1,3,3-pentafluoropropane and/or 1,1,2-tetrafluoroethane. The invention also relates to non-combustible polyetherpolyol and/or polyesterpolyol premixes for producing foam products, especially PU foam. La présente invention concerne des mélanges utiles d'agents d'expansion comprenant HFC-365mfc et HFC-227ea, ainsi que du 1,1,1,3,3-pentafluoropropane et/ou du 1,1,2-tétrafluoroéhane. L'invention a également pour objet des prémélanges de polyétherpolyol et/ou de polyesterpolyol non combustibles utilisés pour produire des produits expansés, notamment des mousses PU.
