Manufacture of PVC The manufacturing plastics often creates large quantities of toxic chemical pollutants such as dioxin, hydrochloric acid, and vinyl chloride.

This poses a severe health risks. Without the addition of additives, pure polyvinyl chloride (PVC) is a brittle white-coloured substance.

During manufacture, PVC is produced in two varieties; rigid and flexible. The rigid type is a particularly durable hard material which exhibits fire retardant properties as well as demonstrating resistance to chemical degradation and weathering, although tends to have low impact.

Vinyl chloride is an organohalogen compound that has important industrial applications. When treated with certain catalysts, vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride, or PVC. PVC is used in the manufacture of numerous products, including packaging films and water pipes.

The vinyl chloride standard controls the labeling that polyvinyl chloride must bear with respect to information on carcinogenicity. Provision 29 CFR (l)(4) requires that containers of polyvinyl chloride shall be labeled as containing vinyl chloride.

Vinyl chloride is used primarily to make PVC, a substance used in products such as pipes. Vinyl chloride is a colorless gas that burns easily.

It does not occur naturally and must be produced industrially for its commercial uses. Vinyl chloride is used primarily to make polyvinyl chloride (PVC); PVC is used to make a variety of plastic products.

Newer varieties of occupational lung diseases primarily due to the vast increase in industrial technology have been reported recently. Preeminent among such newer agents are vinyl chloride (VC) and polyvinyl chloride. Very few cases have been reported, in Europe only, with descriptive histopathologic changes.

To our knowledge, no pathologic studies of VC exposure have been described in the Cited by: CHAPTER 1: INTRODUCTION TO POLYVINYL CHLORIDE Polyvinyl chloride (PVC) was first manufactured in Germany in as a robust and lightweight new plastic.
