Solid semi-solid foam

Semi-solid & solid foam

Semi-solid (or semi-rigid) and solid foams constitute a state commonly sought after in many industrial sectors, from the food industry to construction and automobiles.

Food-grade foams are good examples of semi-solid foams; bread, sponges or synthetic foams (polyurethane, polypropylene, etc.) are good examples of solid foams.

The sensitivity of semi-solid and solid foams

Semi-solid foams, manufactured by air injection in a formulation generally containing both surfactants and gelling macromolecules, like solid foams, formed by solidification (polymerization, gelation, drying) of its liquid component, pose challenges industrial linked to strong couplings between material and process.

In the formation of semi-solid foams, air injection and mechanical mixing conditions play as important a role as the composition of the formula. The final texture and its stability are also key issues.

In the formation of solid foams, the solidification mechanism, often associated with expansion phenomena, also raises questions related to the thermal, homogeneity and mechanical strength of the finished product.
