Is terylene a thermosetting plastic

Witryna23 wrz 2024 · The bonding process: When thermoplastic polymers are heated they become flexible. Thermoset polymers do not soften when heated because the molecules are cross-linked together and remain rigid. The chemical bonding formed within a polymer, and the shape of the resulting polymer, affect its properties. WitrynaA thermoplastic is a polymer that becomes pliable/moldable upon heating, and then returns to a solid (keeping its new shape) when cooled. Thermoplastics are generally high molecular weight polymers with very few or no crosslinks. Polymer chains are held together by intermolecular forces (most often van der waals) and physical …
