MULTI-LAYER NONWOVEN FABRIC (MNF)
The fabric is made on the basis of a basalt superthin fiber (BSTF). MNF consists of
three layers: two external - from natural, synthetic fibers or their mixes; internal - from
basalt superthin fibers. It is applied as thermal protection of various surfaces in an
interval of temperatures from -250 °Ñ up to + 720 °Ñ.

The multi-layer nonwoven fabric differs in small density, low heat conductivity and
can be used in a wide interval of temperatures. It is possible to make easy mobile
habitation of it for cattlemen, geologists, a subbase of linoleum, thermal protection, etc.
