ABSTRACT:
A stabilized powdered endothermic blowing agent which is a mixture of polycarboxylic acid and an inorganic carbonate, the polycarboxylic acid and the inorganic carbonate each having been surface treated with a component which prevents water from being absorbed thereby. The blowing agent is incorporated into a composition for producing foamed products. Additives may be added to the composition which function in conjunction with the blowing agent to cause surface migration of the additives and/or improve weld line strength of the foamed products.
