Possibility of describing process of formation of polyurethane foams by the use of foaming parameters

  • Published:
Mechanics of Composite Materials Aims and scope

Conclusions

  1. 1.

    It has been shown that the process of PUF formation under near-adiabatic conditions can be described quantitatively by the process parameters τst and τg, with formal utilization of the methods of chemical kinetics.

  2. 2.

    Feasibility has been demonstrated for predicting the behavior of commercial foaming systems in relation to the temperature.

  3. 3.

    It has been shown that τst, in contrast to τg, is not a kinetic parameter; therefore, for a commercial system used in preparing PUF, τst and τg are described by different values of the effective activation energy, which are in turn different from the values of activation energy for urethane formation.
