What is made of PVC

May 15, 2019

PVC may be manufactured from either naphtha or ethylene feedstock. However in China, where there are substantial stocks, coal is the main starting material for the Calcium carbide process. The acetylene so generated is then converted to VCM which usually involves the use of a Mercurybased catalyst. The process is also very energy intensive with much waste generated.
