 Film-forming fluoroprotein foam concentrates is made up of fluoroprotein foam extinguishing agent added with fluorocarbon surface active agent, filming additive, hydrocarbon surface active agent, etc.It can form safety film on the surface of the burning oil which can control evaporation of oil.with the dual effect of foam and safety film,it can control and extinguish the fire in a much shorter time with high efficiency.it has good anti-inflammable fires and close capability. It is a highly efficient foam extinguishing agent with the yield point lower than -10¡æ. It is widely used in oilfield, refinery, oil depot, ships, port, airport, etc. The agent shall be stored in a dry, cool and well-ventilated room with the temperature between ¨C5¡æ~40¡æ. The shelf life is 2 years.
