Napalm is a thickening/gelling agent generally mixed with petroleum or a similar fuel for use in an incendiary device, primarily as an anti-personnel weapon. "Napalm" is a combination of the names of two of the constituents of the gel: naphthenic acid and palmitic acid. "Napalm B" is the more modern version of napalm and, although distinctly different in its chemical composition, it is often referred to simply as "napalm". Colloquially, napalm has been used as the generic name of several flammable liquids used in warfare, often forms of jellied gasoline, such as to be expelled by flamethrowers in infantry and armored warfare. Napalm B is chemically distinct from its predecessor Napalm. It is usually a mixture of polystyrene and benzene, used as a thickening agent to make jellied gasoline. One of the advantages of this new mixture lies in its increased safety while being handled and stored. Many accidents had been attributed to personnel smoking around stockpiles.
