thermosetting
That property which enables a material to be
hardened, or fused and hardened, by means of heat.
Materials having this property are called
"thermosets." Once hardened they cannot
subsequently be softened by reheating. The
synthetic resins, according to the manner in which
they react to heat, are classified as either
thermosetting or thermoplastic. (179 , 233 )
