PVC
is the second largest commodity plastic after polyethylene with
world production currently over 18 million tonnes a year.
The
chemical process for making PVC involves three steps: first, production
of the monomer, vinyl chloride; then the linking of these monomer
units in a polymerisation process; and finally the blending of the
polymer with additives.
