It is a kind of high efficient foam extinguishing agent with fine fluidity , tigh- sealing, fast extinguishing and long term storage. This products not only has the general foam extinguishing agent’s function of cooling and isolate from oxygen, but aslo can forming a water film to inhibit evaporation of ful. Because o f the foam and water film’s twice protecting, it has higher efficient of fire fighting. It can be put out the non- polar liquid and solid fire. The product is widely used in oil field, oil refineries, oil depots, oil tanker, wharf large-scale chemical plants, chemical fiber plants, petrochemical enterprises, chemical products warehouses, and other distillery.
It is mathced with the low expansion foam extinguishing agent equipment and system.
