- Abstract
- This is part of the study to investigate the effects of molecular weight and thermal stability on flammability characteristics of polymeric materials. The results on piloted ignition and on flame spread were already presented. These results clearly show significant effects of molecular weight through the viscosity of the molten polymer on flame spread and also the combined effects of thermal stability and molecular weight on piloted ignition. Since gasification rates necessary for piloted ignition and for a traveling flame front are relatively small, a further study was needed to investigate these effects for cases in which more vigorous gasification occurs.
