Abstract

PURPOSE: To obtain the titled foam having low harmfulness with suppressing the amount of formed formaldehyde, by reacting an aqueous solution of a procondensate of urea formaldehyde having a specific molar ratio of formaldehyde to urea with a flamable and curable solution.
CONSTITUTION: (A) An aqueous solution of a precondensate of urea formaldehyde having a molar ratio of formaldehyde to urea 1.2W1.4 and (B) a foamable and curable solution, e.g., an acidic solution comprising alkylbenzenesulfonic acid, etc., for example, are sent to a foaming machine and molded to give the desired foam. The component A, for example, is obtained by reacting urea with formaldehyde in an alkali aqueous solution, followed by reacting them further in a weakly acidic condition.
USE: Having low thermal conductivity and being slightly combustible, useful as a heat insulating material, warm material, low-temperature insulating material, etc.
