- Abstract
- Specific heat release rate is the molecular-level fire response of a burning polymer. The Federal Aviation Administration (FAA) obtains the specific heat release rate of milligram smples by analyzing the oxygen consumed by complete combustion of the pyrolysis gases during a linear heating program. Dividing the specific heat release rate by the rate of temperature rise gives a material fire parameter with the ujnits and significance of a heat (release) capacity. The heat release capacity appears to be a true material property that is rooted in the chemical structure of the polymer and is calculable from additives molar group contributions. Hundreds of polymers of known chemical composition have been tested to date, providing over 40 different empirical molar grout contributions to the heat release capacity. Measured and calculated heat release capacities for 80 polymers agree to within [plus or minus] 15%, suggesting a new capability for predicting flam,mability from polymer chemical structure.
