Polystyrene thermal expansion coefficient

WebFeb 2, 2004 · The coefficient of thermal expansion (α) at ambient pressure of the polystyrene films was found to be in reasonable agreement with values reported for bulk polystyrene. It is important to note that in their work significant shifts in the T g were reported between heating and cooling cycles for thin polystyrene films, creating some … WebPDMS has a thermal expansion coefficient of 310 µm m −1 °C −1 and is thermally stable below 150 °C (Clarson and Semlyen, 1993; Dow Corning Co., 2005; McDonald and Whitesides, 2002). The gas permeability of PDMS and the impermeability of PDMS to liquids are also useful characteristics for some chemical applications, especially in microfluidics.
