WebPolymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of … WebThe glass transition temperature (Tg) is a phenomenon of amorphous polymers. At this temperature, polymers undergo a transition from glassy to rubbery state. Tg is an important feature of polymer behavior. It marks a region of dramatic changes in the physical and mechanical properties. Below Tg: Due to lack of mobility, the polymers are hard ...
