WebWhen heated or chemically applied, a thermosetting resin, also known as a thermosetting polymer, is a liquid material that hardens permanently. The thermoset forms into the desired shape when heated and placed in a mould. Still, the solidification process involves the formation of crosslinks, which hold the molecules in place and alter the ... 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 moulding. Thermoplastics harden once cooled and do not show any changes in chemical property after being heated and cooled multiple times, making them easily recyclable.
