LTA of PP-PE-PS ternary blend

Local thermal analysis of PP-PE-PS ternary blend 

Local thermal analysis (LTA) of PP-PE-PS ternary blend – (left) AM-FM Viscoelastic Mapping Mode image of 60% polypropylene (PP), 20% polystyrene (PS), and 20% polyethylene (PE) by weight. The brighter colors indicate higher modulus. The black dots indicate points where LTA measurements were made. (right) The LTA measurements are color coded with the points in the image and clearly distinguish the different transition temperatures for PS (blue), PE (green) and PP (red). Imaged with the Cypher S, 6 µm scan size. Sample courtesy of Dalia Yablon and Andy Tsou, Corporate Strategic Research, ExxonMobil Research and Engineering.
