Foamed & Solid Foam

Abundant and solid foams are complex materials characterized by a multiphase structure where a gas phase is trapped in a continuous liquid, gel, or solid matrix. They combine lightness, texture, and functional properties sought after in many industrial fields.

At Rheonis, we support your projects around foams – from their development to their industrial transformation – by providing a detailed understanding of their behavior and their physical transitions.

Variety of services for foam and solid foam

Our approach covers:

Characterization of the physical and mechanical properties of expanded and solid foam

Stability, texture, mechanical resistance, elasticity, behavior under stress.

Study of the dynamic behavior of expanded and solid foam

Formation, expansion, deformation, aging, drainage, collapse.

Optimization of formulations and processes for foam and foam

Choice of foaming, gelling, emulsifying or stabilizing polymer agents.

Multi-scale analysis of solid foam and foam

Bubble structure, homogeneity, porosity, gas/liquid/solid interactions.

R&D and industrialization support for expanded and solid foam

From ideation to process validation.

Measure of foam and solid foam

The mosses have a duality of behaviors – between soft materials and porous solids – requiring suitable measurement methods:

• Texture and sensory profile (Texture Profile Analysis, penetration, hardness).
• Rheology and viscoelasticity (deformation, creep, elastic recovery).
• Structure and porosity (microscopy, image analysis, permeability, turbidity).
• Stability and evolution (drainage, coalescence, density, compaction).
• Mechanical properties (compression, rupture, twisting).

Industrial applications

Semi-solid and solid foams are available according to their physical and chemical nature, with varying requirements depending on the sectors:

• Food : protein mousses (egg, milk), carbohydrate mousses (sweets, aerated confectionery), fatty mousses (ganaches, chocolate creams).
• Cosmetics and care : solid surfactant foams (cleansers, shampoos), polymeric or gelled foams (sticks, masks, expanded powders).
• Pharmaceuticals and biomaterials : polysaccharide biofoams, collagen, porous polymers for controlled release matrices.
• Advanced materials : thermoplastic or thermosetting polymeric foams, mineral or composite foams used for insulation, energy absorption or filtration.
