Cons- In the 70's, VCM, an element in PVC, was linked to a rare type of liver disease called angiosarcoma.  Also dioxin in the PVC can cause internal health problems when the chlorine in PVC is burned; this is harmful to those who work to dispose of it.
Why PVC is Better Than Natural Plastics- Biodegradable plastics cost more because the methods have not been perfected yet and would also cause manufacturers to change methods of disposal in order to dispose of the plastic properly.

PVC is considered a synthetic material because it is made from different chemicals and no natural or living things.  PVC is made by combining ethylene with other additives and chemicals which is then put through polymerization in which the single bond form a long chain of chemicals that form PVC.

Specific uses of PVC are mainly pipes, bottles, flooring, tubes, and rigid films.

In 1926, scientists were trying to use the polymerization of PVC to create a way to bond rubber and metal by using a process called dehydrohalogenation.

In the past polyvinyl chloride has been used in many different ways such as electric wire insulation, a verity of coated cloth products, and shock absorber seals.  In 1930 polyvinyl chloride was used to create long wear phonograph records.
