  • How is Vinyl made

Vinyl is made from natural gas and oil, which are cracked to form ethylene. Subsequently, ethylene will reacts with chlorine generated from electrolysis of salt (NaCl) to form ethylene dichloride (EDC), which is cracked to vinyl chloride monomer (VCM). With chlorine content 57%, PVC is less dependent on the limited supply of gas and oil than other polymer. This makes vinyl a unique polymer in its source of raw material. VCM has used as the precursor to PVC production. As a result, VCM is converted to final product called as PVC or vinyl resin. Before PVC resin is used, PVC resin is blended with additives and modifiers, for example, UV stabilizer, impact modifier, plasticizer, and pigment to produce vinyl compound that is used in various application
