Abstract:

As the initial step in a study of the role of polymer melt viscosity in polymer burning behavior, a simpler, non-burning configuration has been examined. Vertical slabs of two types of polypropylene have been subjected to uniform radiative heating on one face. The subsequent melt flow process was monitored by measuring weights, temperatures and flow velocities. A low MW polypropylene flowed freely at temperatures below those for significant degradation whereas a commercial polypropylene of higher MW degraded and gasified extensively. Plans are described for modeling the non-reactive case first.
