Vinyl Chloride Polymer Thermoplast

Polyvinyl chloride commonly referred to as pvc or vinyl is the world s 3 rd most synthesised thermoplastic material. 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. 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.

Polyvinyl Chloride Pvc Plastic Uses Properties Benefits Toxicity

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.

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. Rigid vinyl also known as unplasticized polyvinyl chloride upvc is a strong and lightweight film. 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.

Polyvinylchloride pvc or vinyl is a thermoplastic and the third largest production polymer in the world. 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. It is one of the most durable low cost films and is resistant to many chemicals. Pvc can be rigid or flexible clear or opaque.

Pvc comes in two basic forms. It is one of the most analyzed tested and versatile materials on the market. Rigid sometimes abbreviated as rpvc and flexible. A thermoplastic or thermosoftening plastic is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.

Generally upvc can be used at temperatures up to 60 c. Thermoplastic moulding materials for the production of packaging materials for foodstuffs which consist of or are based on vinyl chloride polymers and contain monoalkyl tin stabilizers.
