dont you love old phonograph records?
Yeah, phonographs are pretty neat! I just learned they were usually made with shellac?
Oh really I thought they were made of vinyl??
Kind of, they started being made with polyvinyl chloride in the 1950's.
HHmmm what was the first record you ever bought?
Polyvinyl chloride
Polyvinyl chloride (; colloquial: polyvinyl, vinyl; abbreviated: PVC) is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene. About 40 million tonnes are produced per year.
PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used in making bottles, non-food packaging, food-covering sheets,
Phonograph record
A phonograph record (also known as a gramophone record, especially in British English, or simply record) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac; starting in the 1940s polyvinyl chloride became common. In recent decades, records have sometimes been called vinyl records, or simply vinyl or even vinyls.
