WebAs mentioned above, polymers that are classified as plastics can be divided into two major categories: thermoplastics and thermosets. Thermoplastics such as polyethylene and polystyrene are capable of being molded and remolded repeatedly. Thus, a foamed-polystyrene cup can be heated and reshaped into a new form—for instance, a dish. WebThermoset Plastics vs Thermoplastics When classified by chemical structure, there are two generally recognized classes of plastic materials: Thermosets, having cross-linked molecular chains and Thermoplastics, which are made up of linear molecular chains. Thermoset polymers require a two-stage polymerization process.
