Thermoset

Definition(s)


Thermoset

Plastic which, when cured by application of heat and/or chemical reaction, changes into a substantially infusible and insoluble material.

  • Note: 1 to entry: Unlike in thermoplastics, the curing process in thermosets creates a chemical bond that prevents the material from being remelted.
