Naphtha type/Wide Cut Jet Fuel

Naphtha-type jet fuels have a lower freezing point than kerosene-type jet fuels, making them preferable in high altitudes and colder climates. The grade is known as Jet-B fuel for commercial use. Naptha-type jet fuels tend to have a lower flash point than kerosene-type jet fuels, and are more volatile, making them less popular.
