Poly Vinyl Chloride Monomer

Rigid sometimes abbreviated as rpvc and flexible.

Poly vinyl chloride monomer. Polyvinyl chloride is a white rigid quite brittle solid. Oxychem s affiliate oxyvinyls is the third largest polyvinyl chloride pvc supplier in the united states. Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics. Vinyl chloride is also produced as a combustion product in tobacco smoke.

In practice however vinyl chloride polymerized commercially does not have regular tacticity because the growing end of the chain is a free radical at an sp 2 hybridized carbon. Since vinyl chloride is a monosubstituted ethylene and not a symmetric molecule in principle it could have explicit tacticity as does for example polypropylene. Additives are used to modify the properties of polyvinyl chloride to make it more useful. About 13 billion kilograms are produced annually.

Oxyvinyls offers a full product line of pvc resins suitable for most vinyl. Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year.

Vinyl chloride is a chlorinated hydrocarbon occurring as a colorless highly flammable gas with a mild sweet odor that may emit toxic fumes of carbon dioxide carbon monoxide hydrogen chloride and phosgene when heated to decomposition.

Pvc is used in the manufacture of numerous products including packaging films and water pipes. Polyvinyl chloride pvc is a chlorinated hydrocarbon polymer produced commercially from vinyl chloride monomer ch 2 chcl by free radical polymerization in an aqueous suspension process. Polyvinyl chloride pvc or vinyl is an economical and versatile thermoplastic polymer widely used in building and construction industry to produce door and window profiles pipes drinking and wastewater wire and cable insulation medical devices etc. Pvc comes in two basic forms.

When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc. Vinyl chloride is an organohalogen compound that has important industrial applications. Pvc is used to make a variety of plastic products including pipes wire and cable coatings and packaging materials. This polymerisation reaction proceeds by a free radical mechanism.
