Abstract : Simultaneously monitoring the variation of temperature, foam rising rate, internal foam pressure and
dielectric polarisation, the latter being a direct measure of setting and curing of a thermosetting foam, has
allowed the comparison of the dynamic variation of determinant parameters of polyurethane foams and
of tannin/furanic foams of different formulation and characteristics. This monitoring provides a good
description of the process and possible characteristics of the prepared foam and constitutes an invaluable tool
for foam formulation. Such a comparison indicates that fundamental differences, but also similarities, exist
between the foaming processes of the two More >
