The research is attempting to determine whether or not
chemically incorporated hydrolytically stable phosphorus
systems can produce major improvements in fundamental
fire resistant behavior. This chemically incorporated
approach contrasts with the normal industrial method of
physically adding fire retardants to the material
systems. The disadvantage of the current approach
includes the ideas that mechanical properties are
impaired by the physical additives. Secondly, the
additives may be extractable under conditions of use,
possibly even producing unattractive, toxic byproducts.
In contract, the chemically incorporated systems will
not be extracted by detergents or subjected to
environmental degradation by normal humidity in the air.
Preliminary small scale burning tests and dynamic
thermogravimetric analysis methods have been very
encouraging. The NIST project is the first effort
achieving a more fundamental understanding through the
use of cone calorimetry methodologies, which permit
determination of heat release rate, heats of combustion,
smoke generation, and carbon monoxide generation.
