Web2.19.4.8.1 Glass transition temperature The Tg of cured bismaleimide ranges from 220 °C to 350 °C. For example, Tg of bis (4-maleimidophenyi) methane cured at 160–180 °C for 2 h … WebThe melting point of polypropylene, for example, is 175°C (347°F). For high-density polyethylene, it’s 130°C (266°F). When amorphous polymers are heated, they don’t melt suddenly. Instead, they reach a range of temperatures over which the material becomes less glassy and more rubber-like or vice versa.
