Prepared mostly by additional polymerisation.
Mostly processed by conventional methods such as injection molding, extrusion and blow molding.
Examples include polyethylene (PE), polyethylene terphthalate (PET).
Thermosetting plastics

3 Dimensional with multiple crosslinks.
Prepared mostly by condensation polymerisation.
Mostly processed by special methods such as compression, transfer and casting.
Examples include Phenol formaldehyde, melamine formaldehyde.
