A major obstacle in the analysis of some fluoropolymer systems is the determination of the polytetrafluoroethylene (PTFE) content. This can be accomplished using a differential scanning calorimeter (DSC). Pure PTFE exhibits a crystalline melt between 570[K and 610[K. PTFE in a mixture continues to exhibit this same characteristic melt temperature.
