Medium
expansion foam extinguishing agent has larger expansion ability than low expansion
foam extinguishing agent. This foam extinguishing agent will produce exquisite
medium expansion foam. And its foam quality is higher than high expansion foam
extinguishing agent. So it can not only be used as high expansion foam
extinguishing agent, but also cover large range of water-insoluble and flammable
flowing liquid.
