'aminoplastic' originates from 'amino' and 'plastic', where 'amino' refers to compounds containing an amino group and 'plastic' refers to materials that can be molded.

'aminoplastic' was derived from the combination of 'amino' and 'plastic' in the 20th century to describe plastics made from amino resins.

Initially, it referred to any plastic made from amino resins, and this meaning has largely remained the same in modern usage.
