Physical Properties of Polymers Handbook · Flammability

Abstract

The flammability of a polymer is an interaction of pyrolysis, ignition, combustion, flame propagation, and flame extinction processes. The processes are brought about by the heat exposure of the polymer. Heat and products are generated in pyrolysis, ignition, combustion, and flame propagation processes, presenting hazards to life and property. For the assessment of thermal and nonthermal hazards, fire prevention and protection, several types of models have been developed. All these models use fire properties of polymers associated with pyrolysis, ignition, combustion, and flame propagation as inputs. These properties are listed and discussed in this chapter. Three test apparatuses and methods have been developed to determine the fire properties associated with flame propagation: (1) ASTM D 2863 oxygen index test method for downward flame propagation for small samples; (2) ASTM E 1321-90 lateral ignition and flame spread (LIFT) test method for horizontal and lateral flame propagation; and (3) the fire propagation index (FPI) test method for vertical flame propagation. Several fire properties are associated with fire suppression/ extinguishment by active and passive fire protection techniques. Changes in the values of the properties are used to assess the effectiveness of the techniques. The fire property associated with corrosion damage is defined as corrosion index (CI), which is the corrosion rate per unit mass concentration of the products. The fire property associated with smoke damage is the ratio of the yield of smoke-to-the yield of CO2.
