Foaming agent composotion contaning hydrofluoric carbon, lower boiling alcohol and/or lower boiling carboxyl compound

摘要

The present invention relates to blowing agent compositions that contain at least one hydrofluorocarbon having a boiling point of 30 °C or higher and lower than 120 °C, at least one hydrofluorocarbon having a boiling point lower than 30 °C, and at leat one component selected from low-boiling alcohols and low-boiling carbonyl compounds. The present invention also relates to processes for preparing polymeric foam using such blowing agent compositions, as well as polymeric foams and foamable polymer compositions containing such blowing agent compositions.
