 Fluoroprotein foam concentrates is prepared by adding an appropriate amount of fluocarbon surface active agent in the protein foam extinguishing agent. Due to the action of fluorocarbon surface active  agent, the extinguishing agent can be used for extinguishing fires of oil cans in the manner of subsurface injection while used as protein foam extinguishing agent. It can also be used together with powder extinguishing agent with the efficiency of fire extinguishing 1/3 higher than the protein foam extinguishing agent. The agent can be mixed with water in the proportion of 3:97 or 6:94 in various low expansion foam production equipment. It can be widely used for extinguishing large fires in oilfields, oil depots, petrochemical companies, ships, airports and companies with large storage of oils.
The extinguishing agent shall be sealed and kept at a cool, dry and well-ventilated place with the ambient temperature between -5~40¡æ. The shelf life is 2 years.
