About 13 billion kilograms are produced annually.
Polymers vinyl chloride.
Vinyl polymers is a name often used to identify polymers based on the vinyl group nch ch 2 but really has been used to identify polymers and copolymers of vinyl chloride.
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.
Pvc is used in the manufacture of numerous products including packaging films and water pipes.

3904 10 00 00 poly vinyl chloride not mixed with any other substances.
Rigid sometimes abbreviated as rpvc and flexible.
It also has excellent stretch properties at high temperature making it ideal as a material for secondary processing such as vacuum molding.
Pvc vinyl chloride is an organohalogen compound that has important industrial applications.
5 18 60 61 these polymers have been used extensively in the past for corrosion protective systems but they often need large amounts of strong solvents to be apply properly.
When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc.
Pvc comes in two basic forms.
Polymers of vinyl chloride or of other halogenated olefins in primary forms.
