Polystyrene is thermosetting or thermoplastic
Websets and Thermoplastics. Before looking onto ther-moplastic elastomeric materials it is necessary to understand the thermosets and thermoplastics first. 1.1. Thermoset Thermoset is a polymer that is cured by heat or chemical reaction and becomes infusible and in-soluble material. Thermoset polymers have a per-manent irreversible polymerization. WebThe simplest TPE materials are like ABA block copolymers, where: A is a hard thermoplastic at room temperature but soften at elevated temperatures (e.g. polystyrene, polyethylene, or polypropylene) ; B is a soft elastomer (e.g. polydimethylsiloxane, polybutadiene, polyisoprene or poly (ethylene-propylene)); Thermoplastic Styrenic Block Copolymers (SBC or TPE-S)
