Some other examples of thermoset plastic polymers include silicones, vulcanized rubber, epoxies, polyesters and phenolics. When frozen, however, a thermoplastic becomes glass-like and subject to fracture. You mix the two parts of epoxy together, mold it to the shape you want, and it sets up, never to be liquid again. Energy and/or catalysts are added that cause the molecular chains to react at chemically active sites (unsaturated or epoxy sites, for example), linking into a rigid, 3-D structure. Thermosetting plastics are ones that, when heated, do not return to a softened, moldable state. Examples of plastic include PVC, acrylic, polystyrene, expanded polystyrene (aeroboard), man-made rubber, polythene (or polyethylene, or PET) and nylon.
