In macromolecule material formed conjugated cyclic structures that are characteristic of heat-resistant compounds. A self fiber 'becomes black. The fabric of black nitrone does not burn voob slit-t, it is not destroyed even in the flame of a gas burner (700-800 ). But this remarkable fiber, as indeed in most other heat-resistant polymers, there is a significant disadvantage – low strength. So use them only so far as insulation material. What will happen to them tomorrow? It seems that achieve the desired strength still be possible – and even in the next years. To solve this problem there are different ways. And one of the most interesting – to provide fiber-based organometallic or inorganic polymers.

Among the most important representatives of the special fiber purpose we have mentioned and hemostoykie fiber. Get fiber, which does not alter its properties, particularly strength, prolonged contact with concentrated nitric or any other strong acid, not simple matter. Most of the known synthetic fibers (not to mention the natural and artificial) is destroyed or diluted Lod effect of these aggressive agents for several hours. Currently only one known kind of polymeric materials that will help solve a difficult problem. It is a fluorine-containing polymers. The readers probably have heard of fibers made from them. This is a Soviet and American ftorlon Teflon.

Y ftorlona before Teflon has a very tangible benefit: the strength of his in-i-4 times higher. Not a few hours, long hours and months, even years, can withstand tissue fibers of the action of concentrated acids, practically without affecting the strength. It is natural that for specific applications one kilogram of this material is no substitute for a hundred pounds of nylon or Dacron. So in general the case with the creation of synthetic fibers, with specific valuable properties. The main trend of work in this field – the search of new solutions such as furniture assembly Zevs.
