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. 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.
