PVC (polyvinyl chloride) is one of the oldest and most important plastics materials, with its first use in production dating back to 1913.
PVC is a high polymer produced by the addition, end to end, of molecules of chlorine and vinyl, consisting of carbon, hydrogen and chlorine.
The raw materials of PVC are 57% sodium chloride or salt (present in underground deposits or in the sea) and 43% derivatives of petroleum.

In order to be used, the raw material generally known as "PVC resin" needs to have added to it various products which give it the characteristics required for each of its very many applications. The production of these mixtures is achieved by extrusion (sections) or injection.

Its main characteristics are:

Maintenance: this material requires no maintenance and can simply be wiped down with a sponge

Impermiability to water and air, providing good sound and heat insulation

Robustness: it has a good level of shock resistance

Resistance to ageing, UV rays and most aggressive agents.

Its main applications are in public works and building but it is also used in cabling and various furnishings.
