Polyvinyl Chloride (PVC)

PVC (Polyvinyl-chloride) is one of the earliest plastics, and is also one of the most extensively used. It is derived from salt (57%) and oil or gas (43%). PVC is made from chlorine – produced when salt water is decomposed by electrolysis – with ethylene, which is obtained from oil or gas via a ‘cracking’ process. After several steps, this leads to the production of another gas: vinyl chloride monomer (VCM). Then, in a further reaction known as polymerisation, molecules of VCM link to form a fine white powder (PVC). This powder is mixed with additives (stabilisers and/or plasticizers) to achieve the precise properties required for specific applications. The resulting PVC granules (compounds) or ready-to-use powders (pre-mixes) are then converted into the final product.
