thermoplastic
意味: A type of polymer that becomes soft and mouldable when heated and hardens upon cooling, a process that can be repeated without significant chemical change. Also used as an adjective to describe this property.
Thermoplastics — including polyethylene, PVC, polypropylene, and nylon — can be melted and reshaped multiple times, making them readily recyclable. This distinguishes them from thermosets, which undergo irreversible chemical changes when cured. Thermoplastics dominate everyday plastic products, from packaging to car bumpers. In engineering contexts, the term collocates with 'matrix,' 'composite,' 'resin,' and 'moulding.' Understanding the thermoplastic/thermoset distinction is essential in materials science and manufacturing.
