fire retardant
Combustion-slowing substance
Fire retardant is a substance or treatment that slows or prevents the spread of fire.
As an adjective, it describes materials that have been treated or manufactured to resist ignition and burning: fire retardant fabrics, fire retardant foam.
The noun refers to the chemical compound itself, often sprayed from aircraft onto forests during wildfires or applied to building materials, furniture, and clothing.
Fire retardant doesn't make something fireproof—it buys time by delaying combustion rather than preventing it entirely.
