Material properties of duroplastics
Duroplastics, plastics which, after curing, can no longer be deformed by heating or other measures. They contain hard, amorphous, insoluble polymers.
The macromolecules are tightly cross-linked via covalent bonds, which causes their lack of softening when heated, so they can only be machined after curing.
Thermoset parts have good dimensional stability, retain electrical and dielectric properties and are resistant to chemicals or organic solvents even at high service temperatures.
