Open-cell foams contain a substantial proportion of interconnected cells, while closed-cell foams contain cells that are largely separated from one another. Cell connectivity can influence air and fluid permeability, water absorption, thermal behavior, and other properties; for example, higher closed-cell content can be beneficial in some insulation and water-resistant applications. Open- or closed-cell classification alone, however, does not establish whether a foam will be flexible, stiff, resilient, or strong. Those properties also depend on the base material, density, cell size and geometry, orientation, wall structure, manufacturing process, and product configuration.
The relevant manufacturing variables depend on the foam chemistry and production method. Formulation, blowing or expansion conditions, temperature, pressure, mixing or dispersion where applicable, cure or crosslinking, molding, extrusion, bead processing, and other process controls can affect density, cell size and distribution, cell openness, dimensional stability, and mechanical properties. Irregular cells, density variation, incomplete expansion or cure where applicable, collapsed regions, or other departures from specified conditions may warrant further examination, but their significance depends on the material, location, extent, and intended use. Representative sections, manufacturing records, microscopy, density measurements, and appropriate physical testing can help assess whether process-related variation is present and relevant to the reported condition.
Heat, moisture, chemicals, ultraviolet exposure, oxidation, or other aging conditions can affect foam properties, but the response depends strongly on the underlying material chemistry and cellular construction. Possible changes may include dimensions, stiffness, resilience, recovery, strength, surface condition, cell integrity, or fluid absorption. Exposure records, dimensional measurements, photographs, material condition, and testing can help assess whether environmental conditions are consistent with the deterioration. Comparisons with unaffected material are most informative when the samples are reasonably similar in composition, density, age, manufacturing history, thickness, and prior loading, and accelerated-aging results should not automatically be treated as direct predictions of long-term field performance.

A bonded foam assembly may separate within the foam, within an adhesive or bonding layer, at an adhesive-to-foam or adhesive-to-substrate interface, within the adjoining substrate, or through a combination of failure modes. Fracture surfaces and exposed interfaces can be examined for foam tearing, adhesive transfer, coverage, surface preparation, contamination, cell damage, substrate failure, and other evidence associated with the separation. Joint configuration, compression, environmental exposure, application records, and appropriate tensile or adhesion testing may also be relevant. When adhesive chemistry, curing, compatibility, or bond performance becomes the principal technical issue, separate Adhesives expertise may be appropriate.
