Polymer which can be remolded again:
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. WebNov 5, 2024 · ABS can be easily liquefied and molded into complex shapes through injection molding techniques. Its 100% recyclability makes it possible to be melted again and again and reshaped without any chemical degradation or burning. ABS is considered a very “safe to handle” plastic since it cools down and hardens quickly.
