Polyvinyl chloride is formed in flat sheets in a variety of thicknesses and colors. As flat sheets, PVC is often expanded to create voids in the interior of the material, providing additional thickness without additional weight and minimal extra cost (see closed-cell PVC foamboard ).
Vinyl chloride is an organochloride with the formula H 2 C=CHCl. It is also called vinyl chloride monomer (VCM) or chloroethene. It is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). Vinyl chloride is a colourless flammable gas that has a sweet odor and is carcinogenic.
The 1 through 7 numbers stand for, respectively, polyethylene terephthalate, high-density polyethylene, polyvinyl chloride (PVC), low-density polyethylene, polypropylene, polystyrene or Styrofoam ...
A manufacturer's label may say, for example, 67% polyester, 33% polyurethane for a fabric that contains no PVC; or 80% polyvinyl chloride, 20% polyurethane with mention of the polyester backing omitted. PVC clothing is a highly resistant material and waterproof. [3]
The gas is used to make the polyvinyl chloride hard plastic resin in plastic products. It is found in products such as credit cards, furniture and car parts, but is most notably used in PVC ...
Vinyl chloride, used to make the polyvinyl chloride hard plastic resin in a variety of plastic products, is associated with increased risk of liver cancer and other cancers, according to the ...
PVC and plastic production produces PVC dust [59] [60] with mortality confirmed among vinyl and polyvinyl chloride workers after reanalysis of data [61] and coronary artery disease and cancer death among vinyl chloride exposed workers [62] Rubber chemical manufacturing impacting mortality among these workers.

Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.
