Firefighting Foams	Specialized foams, increasingly fluorine-free, deployed in aircraft rescue operations to quickly suppress fuel fires.
Melamine Foam	An open-cell, lightweight foam employed for sound insulation in cabins and galleys due to its excellent acoustic properties
Polyethylene Foam	A closed-cell, flame-retardant foam utilized in seat support and buoyancy layers for its durability and lightweight nature.
Polyimide Foam	A heat-resistant, low-toxicity foam applied for acoustic and thermal insulation in cabins and engine areas
Polymethacrylimide (PMI) Foam	A high-strength, heat-resistant foam serving as a structural core in composite panels for wings and fuselage sections
Polyurethane Foam	A lightweight, flexible foam used for seat cushions and interior padding, designed to be flame-retardant and shock-absorbent.
Polyvinylidene Fluoride (PVDF) Foam	A flame-retardant, low-heat-release foam used for insulation and sealing in aircraft interiors like overhead bins.
