Polystyrene is a thermosetting polymer
WebPolystyrene is an aromatic polymer, naturally transparent, made up of monomer styrene. Polyvinyl chloride (PVC) is a plastic polymer made of monomer vinyl chloride. ... Such materials are thermosetting plastics. … WebThermoplastic. A thermoplastic is a material, usually a plastic polymer, which becomes more soft when heated and hard when cooled. Thermoplastic materials can be cooled and heated several times without any change in their chemical or mechanical properties. When thermoplastics are heated to their melting point, they melt to a liquid.
