Chlorinated PVC

- May 30, 2019-

PVC can be usefully modified by chlorination, which increases its chlorine content to or above 67%. Chlorinated polyvinyl chloride, (CPVC), as it is called, is produced by chlorination of aqueous solution of suspension PVC particles followed by exposure to UV light which initiates the free-radical chlorination. The reaction produces CPVC, which has thermal and chemical properties that are superior to PVC.
