With low polystyrene content, the material is elastomeric with … WebThis is totally reversible and repeatable. Most linear polymers and branched structure polymers with flexible chains are thermoplastics. This is in contrast to thermosetting polymers, which do not soften when heated due to strong covalent crosslinks. Thermoset polymers are generally harder and stronger than thermoplastics and have better ...
WebMay 16, 2024 · As the names imply, thermoplastic polymers soften and become plastic or rubbery when heated, whereas thermosetting types become “set”, that is they harden irreversibly when heated. Cellulose acetate and nitrate are examples of thermoplastic polymers and Ebonite , which is highly crosslinked rubber, is a typical thermoset polymer. WebA thermoplastic is a class of polymer that can be softened through heating and then processed using methods such as extrusion, injection moulding, thermoforming and blow …
