What kind of plastic is used in making a compact disc?
CDs are made from almost-pure polycarbonate plastic. A thin layer of aluminum or sometimes gold is applied to the surface to make it reflective. This in turn is protected by a lacquer film.
What is the CD made of?
A Compact Disc is made from a 1.2 mm thick disc of almost pure polycarbonate plastic and weighs approximately 16 grams. A thin layer of aluminum or, more rarely, gold is applied to the surface to make it reflective, and is protected by a film of lacquer. The lacquer is normally spin coated directly on top of the reflective layer. On top of that surface, the label print is applied.
