Class A Environmentally Friendly Extinguishing Foam Agent(MJABP)

Class A Environmentally Friendly Extinguishing Foam Agent(MJABP)

Product overview:

The Class A foam fire extinguishing agent is featured as fast firefighting speed, high water efficiency, thermal insulation, long wall-hanging time, remarkable anti-recombustion effect, which can greatly reduce the loss of water on fire site. Moreover, due to the fullness, fineness, good durability and high moisture content of its foam, it can form thick foam layer on vertical & other angular surface and even on the top of residence building.

This product is featured as stable foam, high fire extinguishing efficiency and good re-combustion prevention effect, which is a desired product to extinguish the fires caused by Class A substance. In addition, it is applicable to various Class A fires caused by rubbers, coals, papers and building materials.

Principle of Class A foam fire extinguishing agent :

Class A foam fire extinguishing agent can form an aqueous film thermal insulation layer on the surface of combustion substance, whose foam is stable, durable and balanced in drainage. Furthermore, this agent is of good wetting and permeability which can penetrates into deep cracks of solid combustion substance to extinguish the smoldering fire, achieving complete fire extinguishing without re-combustion.
