Polymer thermoplastic

WebThese polymer molecules consist of long chains which have only weak bonds between the chains. The bonds between the chains are so weak that they can be broken when the plastic is heated. The chains can then move to form a different shape. The weak bonds reform when it is cooled and the thermoplastic material keeps its new shape. WebThermosetting vs. Thermoplastic. Thermoplastics, also known as thermo-softening plastics, consist of a polymer that becomes pliable or moldable beyond a certain temperature, and then returns to a solid state upon cooling. Examples include polyethylene, polypropylene, polystyrene, polyvinyl chloride, and polytetrafluoroethylene (PTFE).
