Dichloroethane is the product that starts the PVC chain
What is it used for?
The chemical compound 1,2-dichloroethane (DCA) - commonly known by its former name ethylene dichloride (EDC) - is obtained from ethylene by cracking petroleum combined with chlorine.
EDC is used to produce vinyl chloride monomer (VCM, or chloroethane), which in turn - through a polymerisation process - is used to make polyvinyl chloride or PVC.
It can also be used as an intermediate in chlorinated solvents, in paint, varnish and finish removers, as a metal degreaser and as an intermediate in organic synthesis.
Ercros produces DC from the chlorine manufactured at its Vila-seca I plant. Depending on the demand for chlorine in the rest of the company's production, the need for EDC is met by purchasing external products.
