Duroplasts

Duroplasts, also known as thermosets, are plastics that can no longer be deformed after they have hardened. Thermosetting plastics are hard, glass-like polymer materials that are strongly three-dimensionally cross-linked via chemical main valence bonds.

Crosslinking takes place when mixing precursors with branching points. It is activated either chemically at room temperature using catalysts or thermally at high temperatures.
