Abstract A foaming agent without chlorofluorohydrocarbon for hard polyurethane foam plastics contains plant acid (2.16-3.84%), aluminium sulfate (2.16-3.84), potassium nitrate (3.6-6.4), urea (4.5-8), propanetriol (7.2-12.8), propanediol (19.8-35.2), acetone (19.8-35.2), oil (23.4-41.6), flame-retarding agent (4.5-8), water (1.8-3.2) and cyclohexane (1.08-1.92). Its advantages include no poison and harm and high density and insulating effect. It can replace freon.
