Fire-Resistant Armor
From Lostech Wiki
Fire-Resistant Armor is a special type of armor that negates all heat damage from enemy weaponry. It's used by battle armor to protect from flamers, inferno rounds, and other heat based weapons. It has yet to be seen on any battlemechs, vehicles, or aircraft.[1]
This armor was used by the Capellan Confederation to create their Heat-Dissipating Armor in 3123.[2]
