Rigid sometimes abbreviated as rpvc and flexible.
Vinyl chloride polymer thermoplast.
Polyvinyl chloride commonly referred to as pvc or vinyl is the world s 3 rd most synthesised thermoplastic material.
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 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.
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.
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.
Generally upvc can be used at temperatures up to 60 c.
Poly vinyl chloride pvc in particular has been subjected to such modification by a variety of material and its use in electrical applications especially in rubberized form is well known 4 with the advent of thermoplastic elastomers one would expect that the conventional materials in pvc rubber blends would be replaced by new components.
Pvc comes in two basic forms.
A thermoplastic or thermosoftening plastic is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.
