Effectiveness in confined spaces Moderate (need high concentration, ventilation issues) High (uniform dispersion at low mass concentration)
Compatibility with electronics Poor (water, foam damage; dry powder risk) Excellent (non-conductive, residue-free options)

Silica andClay Nanopaterles

Nano-silica (SiO₂) and montmorillonite clays are used to create stable, non-toxic foams and gels. These materials are both chemically inert and thermally stable, making them suitable for prolonged exposure to high heat. They can also be functionalized with flame-retardant molecules (e.g., phosphorus or nitrogen compounds) to provide multiple suppression mechanisms.

Encapsulated paraffilnn or salt hydrates in a nano-sized shell can absorb large compats of latent hat when they y melt. When integrated into a sumpressant, these PCM s provide sustainate ehighed cololing, especially useful in deep-seated fires such as those in upholstery or stold materials.
