Examples of thermosoftening plastics

WebThermosoftening Plastics are polymers that can be manipulated into different shapes when they are hot, and the shape sets when it cools. If we were to reheat the polymer again, we could re-shape it once again. Modern thermosoftening plastics soften at temperatures anywhere between 65 oC and 200 oC. In this state, they can be moulded in a number ... WebJul 25, 2024 · They are examples of thermoplastics (thermosoftening plastics), because they can be heated to make them softer - more plastic, reshape it e.g. in an injection mould system, and on cooling the plastic object retains its new shape - bottle, bowl, toy etc.
