Polyvinyl chloride,
commonly abbreviated PVC, is a thermoplastic polymer. It is a vinyl
polymer constructed of repeating vinyl groups having one hydrogen
replaced by chloride. Polyvinyl chloride is the third most widely
produced plastic, after polyethylene and polypropylene. PVC is widely
used in construction because it is cheap, durable, and easy to assemble.
PVC production is expected to exceed 40 million tons by 2016. According
to IUPAC, polyvinyl chloride should be named poly (chloroethanediyl),
but the name is not used. |

It
can be made softer and more flexible by the addition of plasticizers,
the most widely used being phthalates. In this form, it is used in
clothing and upholstery, electrical cable insulation, inflatable
products and many other applications in which it would originally have
replaced rubber. |

Polyvinyl chloride is produced by polymerization of the vinyl chloride monomer (VCM), as shown. |

The product of the
polymerization process is unmodified PVC. Before PVC can be made into
finished products, it almost always requires conversion into a compound
by the incorporation of additives such as heat stabilizers, UV
stabilizers, lubricants, plasticizers, processing aids, impact
modifiers, thermal modifiers, fillers, flame retardants, biocides,
blowing agents and smoke suppressors, and, optionally pigments. |

The properties for PVC are usually categorized based on rigid and flexible PVCs. | |||||||||||||||||||||||||||||||||

While processing Plastogreen PVC
average content of PVC remains between 60 % - 70 % and balance portion
remains wood waste and additives. Plastogreen PVC is used for making water proof
MDF boards, Hollow doors, Frames, Filler boards. |
