Increase the temperature of pyrolysis and the mechanism of flame retardancy

The introduction of aromatic or heterocyclic molecules in the fiber, increase the intermolecular density and cohesion, improve the heat resistance of the fiber; or by crosslinking cyclization, formation of complexes with metal ions and other methods to change the molecular structure of the fiber, improve the degree of carbonization, inhibit thermal cracking, reduce the production of combustible gas.
