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 ... The glass–liquid transition, or glass transition, is the gradual and reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle "glassy" state into a viscous or rubbery state as the temperature is increased. An amorphous solid that exhibits a glass transition is called a glass. The reverse transition, achieved by supercooling a viscous liquid into the glass state, is called vitrification. shanola shamelessWebBlind fasteners专利检索，Blind fasteners属于 .用形状记忆材料专利检索，找专利汇即可免费查询专利， .用形状记忆材料专利汇是一家知识产权数据服务商，提供专利分析，专利查询，专利检索等数据服务功能。 poms elapsed years
