Thermoset

A thermoset is a material that has been cured using thermal curing (generally heating above 200 degrees celsius). Thermoset polymers are plastics that have been generated using heat to crosslink the molecular chains. This in turn means the process is irreversible. The same goes for all other thermoset material. Thermoset means the process that created the material cannot be undone.
