How to Make PVC?

The manufacture of PVC consists of the following five main steps:

Ethylene and Chlorine gas Production: Ethylene gas and chlorine gas are the two basic materials used in the production of vinyl. Ethylene gas is purified from petroleum or natural gas, while chlorine gas is synthesized from sea salt by high-energy electrolysis.
Vinyl Chloride Monomer (VCM) Production: Ethylene dichloride (EDC, also known as 1,2-dichloroethane) can be produced from chlorine and ethylene by either chlorination or oxychlorination. EDC is then converted into VCM by a reaction known as pyrolysis.
Polymerization of VCM into Polymer: VCM molecules are linked together to produce PVC, which is usually a white powder.
Formulation or Compounding: Pure PVC is mixed with additives, such as plasticizers, stabilizers, colorants, etc., to produce usable plastics with the desired properties.
Molding: The formulated plastics are molded into final products such as wall panels, pipes and cables.
