COVERING ARTICLE FOR REACTIVELY EXTINGUISHING A FIRE

A cover article for reactive fire extinguishing is made from a material having a flexible, soft, fibrous woven or non-woven base with a reactive coating in the form of a flexible layer permanently applied on said fibrous base on the article side that is expected to come in contact with a fire hazard, said layer containing a soft, flexible polymer carrier with microcapsules dispersed therein, said microcapsules having a core that contains a fire extinguishing agent or a mixture of fire extinguishing agents characterized by the fact when they are heated to a temperature above their boiling point, they are subject to intensive gas evolution and thermal decomposition with formation of heavy free radicals, and a shell characterized by a narrow range of decomposition temperatures above the boiling point of the fire extinguishing agent.
