Through the use of a combination of all of the declared essential features achieved by obtaining a multilayer cladding non-flammable heat-resistant elastic material having low permeability and high resistance to oils. Flame retardants for textile impregnation bases are aqueous solution of fosforo - and nitrogen-containing compounds. When processing textile fundamentals on the basis of the rotation of the cellulose with the formation on the surface of the fibers durable graphite-like coke, that reduces the heat transfer from the flame to the textile base, prevents the effect of the active parts of the flame and oxygen on the material, reduces the amount of gases and tars.

When processing tissue on the basis of chemical fiber action used flame retardant is in the formation of a protective layer, preventing the fabric from oxygen, retaining volatile resins in the combustion process and prevent the spread of flame. Released by the action of high temperatures, the ammonia reduces the concentration of combustible gases and reduces the ignition temperature.

Impregnation of the textile basis with an aqueous solution of a flame retardant gives incombustibility and helps to stabilize the structure of the tissue and its seal, which provides uniformity of properties in the longitudinal and transverse directions, the uniformity of the adhesive bonding with the polymer layer, the decrease in vapor.

Use as polymeric layer polivinilkhlorida in a relationship with softeners helps to ensure a flexible oil-resistant polymer coating. High cohesive strength between macromolecules polyvinyl chloride obuslovennoe belongs to the group of polymeric materials with reduced Flammability due to released by burning chlorine, which reduces the concentration of combustible gases. Use in the polymer compositions of fosforo - and chlorine-containing plasticizers gives a synergistic effect, resulting in increased resistance of the polymer coating.

The additional introduction of the polymer coating of flame - retardants are compounds of aluminum, magnesium, antimony promotes the formation of graphite-like substances or non-combustible carbon foam, which prevents the spread of flame; and the emergence in the surface layers of the material of the active molecules, inhibiting the combustion of the material in predplamennyh area.

In conjunction with the declared textile base, temperature, composition of the polymer coating and the ratio of the layers in the material there is an additional interaction of the flame retardant in the impregnated fabric with a polymer layer including a flame retardant coating that provides additional synergistic effect in slowing down the process of burning material.
