thermoplastic resin
Definition
Noun: A thermoplastic resin is a type of polymer material that becomes soft and moldable when heated and returns to a rigid state when cooled. This heating and cooling cycle can typically be repeated many times without significantly degrading the material's properties.
Usage
The term "thermoplastic resin" is used to describe the raw polymeric material before it is shaped into a final product. It refers to the class of plastics defined by their reversible physical change with temperature. * Polypropylene is a common thermoplastic resin used for food containers and automotive parts. * The recycling process involves melting down thermoplastic resin from old products to form new ones.
Advanced Usage
- As a material class: The term is often used in technical and industrial contexts to differentiate from , which undergo an irreversible chemical change when heated and cannot be remelted.
- For this application, a thermoplastic resin was chosen over a thermoset for its recyclability.
