Anal. Polymer made from styrene is known as polystyrene. Styrene-ethylene-butylene-styrene, also known as SEBS, is an important thermoplastic elastomer (TPE) which behaves like rubber without undergoing vulcanization.SEBS is strong and flexible, has excellent heat and UV resistance and is easy to process. At room temperature, the thermoplastic polymer is a solid but when heated above 100 °C it flows.
