Abstract
A foamed polymer system includes a blowing agent performance enhancer to ensure that the foaming rate of the blowing agent is sufficient to achieve the desired foam characteristics and to improve control over the blowing agent performance. The system includes a combination of an azo-type compound with a metallic salt of an organic acid in the manufacture of the foamed polymer.
