Summary
The foam morphology is very sensitive to the kind of the starting poly(siloxane), to the thermal regime of foaming, and to the type and the concentration of the fillers. While the formation of the polymer foam by injection molding is governed by the polymer melt surface tension and viscosity, the solubility and diffusivity of the blowing agent within the melt [9], the foam formation during the poly(siloxane) crosslinking is strongly influenced by the crosslinking reaction rate. The curing rate depends on temperature and on the concentration of the terminating groups in the polymer molecular structure. Investigation of the foaming mechanism with and without fillers is very important in order to fabricate foams with tailored microstructure and physical properties.
