Pebax glass transition temperature
WebThe glass transition temperature of a dry and a humidi-fied sample of Nylon are shown in Figure 1. The Tg of both samples is shown as a peak in the tan δ. It is clear that humidity acts to plasticize the material and hence reduce the glass transition temperature significantly. A decrease in Tg of nearly 40 °C is observed. WebJan 1, 2015 · The glass-transition temperature (Tg) is about −50 °C due to the flexible segment (Patel and Spontak 2004 ). Through a proper combination of the polyamide and …
