The Class A foam fire extinguishing agent can not only extinguish fires quickly, but also has the effect of heat insulation and radiation protection, and can reduce the possibility of re-ignitionoamed through the compressed air fire extinguishing system. The foam is rich and fine, and can directly adhere to the surface of combustible materials to extinguish fires and prevent the spread of thermal radiation. used in Class A ( wood, paper, fabric, rubber, etc. ) fires. Class B fires (kerosene, gasoline and other flammable liquid fires), various Class A compressed air foam fire extinguishing system devices in places such as fire trucks, airports, gas stations, rubber factories, lumber factories, food processing plants, large oil fields, refineries , etc. middlesuitable for fresh water, not sea water. When extinguishing fire, it can be mixed with fresh water at a ratio of 0.5% to 3% according to the actual situation.Product Description
Class A Fire Foam ( MJABP ) is a new type of high-efficiency fire extinguishing agent suitable for Class A fires. Nowadays, Class A fires are becoming more and more complex, which makes it much more difficult to extinguish. The traditional fire-extinguishing agents such as water and ordinary foam liquids has low efficiency and large water consumption, making it impossible to extinguish the fire quickly. After the fire is extinguished, it is easy to re-ignite. Our company's new The Class A foam fire extinguishing agent can not only extinguish fires quickly, but also has the effect of heat insulation and radiation protection, and can reduce the possibility of re-ignition. Class A Fire Foam ( MJABP ) are foamed through the compressed air fire extinguishing system. The foam is rich and fine, and can directly adhere to the surface of combustible materials to extinguish fires and prevent the spread of thermal radiation. It can also penetrate into the interior to prevent re-ignition and achieve fire extinguishing efficiently
Application
Widely used in Class A ( wood, paper, fabric, rubber, etc. ) fires. Class B fires (kerosene, gasoline and other flammable liquid fires), various Class A compressed air foam fire extinguishing system devices in places such as fire trucks, airports, gas stations, rubber factories, lumber factories, food processing plants, large oil fields, refineries , etc. middle. This product is suitable for fresh water, not sea water. When extinguishing fire, it can be mixed with fresh water at a ratio of 0.5% to 3% according to the actual situation.

Product Advantages
This product has a wide range of uses, high efficiency, environmental protection, and safe fire extinguishing and use functions. It has no odor, no pollution, does not corrode equipment, does not produce residues during storage and use, is stable in storage, and is harmless to the body during normal use. In terms of fire extinguishing, this fire extinguishing agent has a high foaming ratio, rich, fine foam, and strong adhesion. When extinguishing Class A fires, it can quickly extinguish fires, isolate the spread of heat and radiation, and prevent re-ignition; it can extinguish Class B non-water-soluble fires . In the event of a fire, the dual effects of foam and water film can quickly overwhelm the fire and extinguish the fire.
