In the emulsion process, PVC powder is mixed with plasticisers to produce a paste/resin, which is then used for coatings, dipping and spraying.   »  PVC and Its Different Forms The equipment necessary for such a process is typically very expensive. PVC is a polymer with good insulation properties, but because of its higher polar nature the electrical insulating property is inferior to non-polar polymers such as polyethylene and polypropylene. PVC is Biocompatible. It is the world’s third largest thermoplastic material by volume after polyethylene and polypropylene. In fashion, furniture and all types of indoor and outdoor accessories, PVC open up functional and design opportunities that are both visually striking and fundamentally practical. And here's an interesting fact: you can increase the syndiotactic content even more using a couple of tricks. Additives are used to modify the properties of polyvinyl chloride to make it more useful. The properties of the material can be varied by the addition of fillers, plasticizers, stabilizers and colourants. »  What are the main characteristics of PVC? It's currently ranked as the third most widely used plastic in the world (behind polyethylene and polypropylene). »  Methods to Enhance Properties of PVC 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. POLYVINYL CHLORIDE (PVC) PROPERTIES PVC is the most widely used member of the vinyl family. 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. 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. Quick Links to the Detailed Profile:   »  Processing Techniques for Rigid and Flexible PVC This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand. Due to its versatile properties, such as lightweight, durable, low cost and easy processability, PVC is now replacing traditional building materials like wood, metal, concrete, rubber, ceramics, etc. Today, a, Flexible PVC has lower chemical resistance than rigid PVC, Rigid PVC has low continuous service temperature of 50°C, Material Injection Pressure: Up to 150 MPa, Recommended Screw with an L/D ratio of 15 to 18.

It is fabricated efficiently into a wide range of both rigid and flexible products. Disadvantages and advantage Polyvinyl chloride, PVC. Production and Properties of Polyvinyl Chloride. Offers clarity & transparency. Polyvinyl Chloride (PVC) is a thermoplastic made of 57% chlorine (derived from industrial grade salt) and 43% carbon (derived predominantly from oil / gas via ethylene). Heat stabilisers increase the thermal stability, and lubricants reduce the melt viscosity preventing overheating. Polyvinyl Chloride (PVC) is one of the most commonly used thermoplastic polymers in the world (next to only a few more widely used plastics like PET and PP). Polyvinyl Chloride (PVC) Values SPECIFICATION SHEET All information, recommendations and suggestions appearing in this literature concerning the use of our products are based upon test and data believed to be reliable; however, it is the user's responsibility to determine the suitability for their own use of the products described herein. It is most commonly used in pipe and fittings. Chlorinated polyvinyl chloride (CPVC) is manufactured by chlorinating the PVC product, typically increasing its chlorine content from 56% to 66% [2]. Figure 2. When subjected to heat, vinyl compounds initiate a self-accelerating dehydrochlorination reaction and these stabilizers neutralize the HCl produced enhancing the life of polymer.   »  How PVC is manufactured? This process makes PVC strong, lightweight, and durable making it an ideal material for a variety of applications. PVC is a white, brittle solid available in powder form or granules, formed through an addition polymerisation reaction between vinyl chloride monomers (Figure 1). VCM molecules are polymerized to form PVC resin, to which appropriate additives are incorporated to make a customized PVC compound. Polyvinyl chloride (PVC) is a popular thermoplastic that's odorless, solid, brittle, and generally white in color. Extrusion temperatures are 10-20°C below injection molding temperatures in order to avoid premature thermal degradation.
