Abstract

PURPOSE: To provide a novel foaming agent for polyurethane, giving a foamed article containing uniform foams and having excellent uniformity and high insulation, by using chlorotetrafluoroethane as a component.
CONSTITUTION: The objective foaming agent is prepared by mixing (A) a chlorotetrafluoroethane as a high-pressure foaming agent, and if necessary (B) an aliphatic hydrocarbon (e.g. pentane) having a boiling point of 10W50°C and/or a halogenated aliphatic hydrocarbon (e.g. methylene chloride, propyl chloride, etc.) as a low- pressure foaming agent. The weight ratio of (A):(B) is e.g. (20W80):(80W20). The foaming agent is incorporated in the polyurethane raw material in an amount of e.g. 22.5wt%.
