What kind of plastic is used to make lp records?

The type of plastic used is Vinyl. The raw materials for record manufacture were subdivided into those needed to make the master disc, those for actual pressing of the records, and the paper goods needed for labels, sleeves, and jackets. The master disc was made of black lacquer, so it could be etched with grooves to carry the sound. Silver was used to coat the finished disc, and chromium-plated nickel discs were used to press the "vinyl" records.

Records were most commonly made of black plastic, although some were produced in other colors. Recording companies developed the designs for their own labels, sleeves, and album jackets; however, manufacture of these was usually subcontracted to paper suppliers and printers.
