CLASS A FOAM
PRODUCT ORIGIN: Luoyang, China
Class A foam extinguishing agent produces rich, fine and adhesive foams because of the fluorocarbon composite surfactant prepared to be the product by our own company. When extinguishing Class A fire, its foam can not only adhere to the surface of an object and form a thermal radiation protection layer, but also dilute out a strong viscous liquid, which can penetrate deep into the flame of the solid burner, so as to quickly extinguish the fire and prevent re-burn.Class A foam concentrate does not contain any hazardous substances and does not require any special labeling when transported.There is not PFOS and PFOA with C6 technology.
LangChao Class A foam concentrate is effective on smaller class A fires.
