PolyVinyl Chloride (PVC) is the vinyl chloride polimer (CVM). It originates 57% from chlorine and 43% from oil – 38% is carbon and 5% hydrogen and traces of other organic compounds -. It was accidentally synthesized the first time on 1835 by the French chemist and physicist Henri Victor Regnault but its industrial production started around 1950. Chlorine combined with ethylene refined, creates the chloride vinyl monomer (CVM). These molecules connect through a process of polymerization and create the polyvinyl chloride (PVC)
Combining the PVC resin thus obtained (also considering the polymer chains length) with various additives – as fillers, colourants, stabilizers, lubricants and plasticizers – the various formulations to give each product the desired characteristics are created.
