Poly vinyl chloride polyvinyl chloride pvc is one of the worldwide plastic used due to the inherent properties such as durability corrosive resistance low cost and high performance made pvc a versatile polymer with several applications for instance pipes profiles flooring cable insulation roofing packaging bottling and the medical applications.
Vinyl chloride polymer thermoplast.
Most thermoplastics have a high molecular weight the polymer chains associate by intermolecular forces which weaken rapidly with increased temperature yielding a viscous liquid in this state thermoplastics may be reshaped.
A thermoplastic or thermosoftening plastic is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.
Pvc can be rigid or flexible clear or opaque.
Generally upvc can be used at temperatures up to 60 c.
Rigid sometimes abbreviated as rpvc and flexible.
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.
Polyvinyl chloride commonly referred to as pvc or vinyl is the world s 3 rd most synthesised thermoplastic material.
Its most well known application is the formation of pvc pipes in the building and construction industry but the benefits of pvc extend far beyond this into the medical electrical and protective clothing sectors.
