9 Differences Between Thermoplastic And Thermosetting Plastic

WebbThermosetting plastic: “There are some plastics which when molded once, can not be softened by heating. These are called thermosetting plastics.”. Examples of … WebbAnswer (1 of 2): Polyvinyl chloride ( PVC) It is a thermoplastic material. This material is one of which becomes more plastic when heated and becomes rigid again on cooling. Note: … Thermosetting plastics are generally stronger than thermoplastic materials due to the three-dimensional network of bonds (crosslinking), and are also better suited to high-temperature applications up to the decomposition temperature since they keep their shape as strong covalent bonds between polymer chains cannot be broken easily. The higher the crosslink density and aromatic content of a thermoset polymer, the higher the resistance to heat degradation and che… instinctive drives test
