Polystyrene is thermoplastic or thermosetting
WebA thermoplastic, or thermosoft plastic, is a. plastic polymer material that becomes pliable or moldable at. a certain elevated temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. The. polymer chains associate by intermolecular forces, which. weaken rapidly with increased temperature, yielding a.

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 ... WebConsiderations for Thermosets. At Protolabs, for thermosetting plastic, we offer a variety of liquid silicone rubber (LSR) materials. LSR is a common thermoset and is a useful material because of its superior flexibility and heat and chemical resistance. Typical applications include soft-touch surfaces, gaskets, and heat insulation.
