A second way for foaming melts directly is to add a blowing agent to the melt instead of injecting gas into it. Heat causes the blowing agent to decompose and release gas, which then propels the foaming process (Figure 3a). 8 Shinko Wire Company, Amagasaki, Japan, has been producing foams in this way since 1986 with production volumes reportedly up to 1,000 kg per day.
