Abstract

PURPOSE:To obtain the title foaming agent compsn. having excellent compatibility with polyol and storage stability when mixed with polyol and being capable of improving physical properties such as density, closed cell ratio, compression strength, heat conductivity and so on of the final foam, by making up a mixt. of dichlorotrifluoroethane and dichlorotetrafluoroethane with a specific ratio. CONSTITUTION:Dichlorotrifluoroethane is mixed with dichlorotetrafluoroethane in a wt. ratio of 97:3-60:40.
