PVC, in full polyvinyl chloride, a synthetic resin made from the polymerization of vinyl chloride. In addition, it is easily altered by the addition of plasticizers, impact modifiers and other ingredients.

Amorphous density at 25 o C: 1.385 g/cm 3.. Crystalline density at 25 o C: 1.52 g/cm 3.. Molecular weight of repeat unit: 62.50 g/mol. Melting temperature: 240 o C. . In summary, PVC has the following properties: Good physical properties ; Low heat resistance ; Good chemical resistance ; Excellent transparency ; Good flame resistance; Typical End Uses. »  What are the main characteristics of PVC? Poly(vinyl chloride) is the plastic known at the hardware store as PVC. Polyvinyl Chloride structure [2]. PVC is the most sought after polymer material in the building and construction industry and currently accounts for 10.2% of the overall European plastic demand, trailing polyethylene (PE) and polypropylene (PP) [1]. A frequent method of processing PVC involves the suspension of solid particles of the polymer in an appropriate plasticizer. It is the world’s third largest thermoplastic material by volume after, » View all PVC commercial grades and suppliers in Omnexus Plastics Database, » Compare properties of flexible PVC Vs. rigid PVC in detail, Suspension Polymerization accounts for 80% of PVC production worldwide, Take the course - PVC Stabilizers: Decoding the Black Box to Meet Processing & Quality Needs, certain phthalates are now confirmed safe, Manufacturing Long-lasting & Efficient Fuel Cells, Maximize the Resistance of Your Polyurethanes Over Time, 1 Comments on "Comprehensive Guide on Polyvinyl Chloride (PVC)", This is a great article. There are two popular methods for the manufacture of PVC through the addition polymerisation process shown above: In the suspension process, the obtained PVC particles are mixed with plasticisers and can be then extruded in pellets, which are further used for extrusion, calendering, injection moulding and so on. Definition: Polymerization of vinyl chloride (monomer) results in the production of polyvinylchloride or PVC, which is its abbreviated name. 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. It is a naturally white and very brittle (prior to the additions of plasticizers) plastic. Polyvinyl chloride, commonly referred to as PVC or Vinyl, is the world’s 3rd most synthesised thermoplastic material. PVC offers excellent chemical and flame resistance, strength-to-weight ratio and dielectric properties along with good tensile, flexural and mechanical strength, low moisture absorption and exceptional dimensional stability. »  Processing Techniques for Rigid and Flexible PVC, »  Properties Comparison: Flexible PVC Vs. EHC 215: Vinyl Chloride _____ 14 2.2 Physical and chemical properties Some physical properties of VC are given in Table 1. PVC resin obtained from the above processes is extremely unstable due to low thermal stability and high melt viscosity. Offers clarity & transparency. Polyvinyl Chloride (PVC or Vinyl) is a high strength thermoplastic material widely used in applications, such as pipes, medical devices, wire and cable insulation...the list is endless. It is economical and highly resistant to chemicals. Another great posting from Arlington Machinery can be found here: https://www.arlingtonmachinery.com/blog/p.170518001/pvc-recycling-comes-into-its-own/, Your email address and name will not be published, submitting a comment or rating implies your acceptance to. What is Polyvinyl Chloride (PVC), and What is it Used For? Available: https://omnexus.specialchem.com/selection-guide/polyvinyl-chloride-pvc-plastic, [3] KEMI, “Statistics in brief - PVC,” [Online]. A polyurethane blend also offers similar results with increased abrasion and chemical resistance. It can also be easily reprocessed using heat. This lowers the crystallinity of the polymer, increasing its flexibility and ability to be moulded into useful shapes such as containers and packaging. A comparison of some important properties of the two different classes is included in the table below. Additives are used to modify the properties of polyvinyl chloride to make it more useful. Extrusion temperatures are 10-20°C below injection molding temperatures in order to avoid premature thermal degradation. Although flexible PVC also has a range of applications in the construction industry as in flooring, cable insulations, and waterproof linings, its most useful application is in the medical industry. How to process it? A major thermoplastic material with a very wide variety of applications, the essential materials for polyvinyl chloride are derived from oil and salt. Polyvinyl chloride is most widely known for the rigid PVC pipe used in plumbing and water infrastructure systems. PVC comes in two basic forms: rigid PVC (also known as uPVC or RPVC) and flexible (soft) PVC. Figure 2.Compari… © 2021 Matmatch GmbH, All rights reserved. In short, PVC enables us to live better, richer and, p… PVC has excellent electrical insulation properties, making it ideal for cabling applications. We also use them to provide you more relevant information and improve our platform and search tools. It is the world's third-most widely produced synthetic plastic polymer. What it is made up of? There are discrepancies in the literature with regard to Properties of polyvinyl chloride What is Polyvinyl Chloride (PVC), and What is it Used For? The equipment necessary for such a process is typically very expensive. In the emulsion process, PVC powder is mixed with plasticisers to produce a paste/resin, which is then used for coatings, dipping and spraying. When used for car components, PVC thus helps to reduce the risk of injuries in case of accidents. We connect engineers, product designers and procurement teams with the best materials and suppliers for their job. Resulting products can be PVC films, sheets, boards and tubes.
