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). WebMar 16, 2024 · Thermoplastics can be molded and remolded in the presence of heat without losing structural integrity, while thermosets can be molded only once. Of the two, thermoplastics are better suited for all-purpose products that need to be strong and flexible, while thermosets make better high-performance products.
