Maximal cell density predictions for compressible polymer foams
Abstract
Thermodynamic upper bounds for polymer foam cell densities are predicted using compressible selfconsistent
field theory. It is found that the incompressible limit always gives the highest, and therefore
ultimate, upper bound. Qualitative comparisons between the compressible and incompressible cases
agree, indicating that low temperatures and high blowing agent content should be used to achieve high
cell densities. The inhomogeneous bubble structure reveals deviations from the expected homogeneous
SanchezeLacombe equation of state, consistent with some experimental results. A generalized Sanchez
eLacombe equation of state is discussed in the context of its suitability as a simple alternative to the
SimhaeSomcynsky equation of state.
