WebBecause of the amorphous part, semi-crystalline plastics do have a Tg as well. Let's place a Plasticprop sample made of PA6 in the oven. At 50°C, it feels slightly more flexible than it did at room temperature. But if you take it out of the oven again at 60°C, the difference is bigger. PA6 has exceeded its Tg temperature, which is app. 55°C. WebIntroduction to Materials Science. Course 1 of 4 in the Materials Science for Technological Application Specialization.
