Discuss the heat release capacity of polymer derived from microscale combustion calorimeter

Heat release capacity is known as a combination of the thermal stability and combustion properties, which can be used to classify the flammability of materials. It can be derived from microscale combustion calorimeter test results or from additive molar group contributions. PMMA and two kinds of extruded polystyrene were tests by microscale combustion calorimeter with 9 heating rates. Heat release capacity was calculated for the tested materials by 5 algorithms from the literatures. Adaptability of these 5 algorithms was evaluated in this paper.
