Webb15 mars 2024 · Corrosionpedia Explains Glass Transition Temperature (Tg) The temperature at which an amorphous polymer material turns into a viscous liquid or rubbery form when heated is known as the glass transition temperature (Tg).It can also be defined as a temperature at which an amorphous polymer develops the characteristic glassy … Webb5 mars 2024 · • Hard plastics like polystyrene and poly methyl methacrylate are used below their glass transition temperature; that is in their glassy state. Their Tg’s are well above room temperature. • Elastomers like polyisoprene and polyisobutylene are used above their Tg’s, that is in the rubbery state, where they are soft & flexible. 5 7. sharon brophy obituary
