Poly(vinyl chloride), whose international symbol PVC derives from the English name "Poly Vinyl Chloride", is a synthetic thermoplastic composed of carbon, hydrogen and chlorine.
Carbon and hydrogen come from petroleum (43%), while chlorine comes from salt (57%).
Industrial production of PVC dates back to the early 1930s.
It's a plastic that's very much a part of our everyday lives, because its mechanical and physical properties, combined with its ability to be modified to suit specific needs, make it suitable for a wide range of uses.
PVC is used in all sectors of the economy: construction (57% in the European Union), packaging, electricity, electronics, consumer goods, healthcare and transport.
It's the third most widely used plastic in the world (20% of total global plastics consumption, or around 28 million tonnes).
