is a material made from<br />

petrochemicals) and chlorine,<br />
which is extracted from rock<br />
salt or seawater.PVC provides<br />
superior dimensional stability,<br />
durability and non-corroding<br />
and flameretardant properties.<br />
Mixing it with different amounts<br />
and types <strong>of</strong> plasticizers adds<br />
