Is Corian® made from plastic?

No. Corian® is composed for one third of transparent acrylic resin (poly(methyl methacrylate) PMMA) and two thirds natural minerals. The principal among these latter is alumina trihydrate (ATH), a white powder derived from bauxite, the mineral from which aluminium is extracted. It is a mineral material in powder form held together by an acrylic resin.
