Some further uses of flexible PVC include waterproof clothing, life-jackets, inflatables and sporting goods. Available:, [3] KEMI, “Statistics in brief - PVC,” [Online]. We connect engineers, product designers and procurement teams with the best materials and suppliers for their job. Extrusion temperatures are 10-20°C below injection molding temperatures in order to avoid premature thermal degradation. It needs to be modified before being processed into finished products. »  Methods to Enhance Properties of PVC EHC 215: Vinyl Chloride _____ 14 2.2 Physical and chemical properties Some physical properties of VC are given in Table 1. POLYVINYL CHLORIDE (PVC) PROPERTIES PVC is the most widely used member of the vinyl family. 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. Rigid PVC, Ethyleneglycol (Ethane diol) @ 100%, 100°C, Ethyleneglycol (Ethane diol) @ 100%, 50°C. poly(vinyl chloride) information, structure, and properties. General information on PVC is provided here in Chapter 1, followed by introductions on four aspects of PVC; production, characteristics, safety and applications. Processing equipment is typically very expensive. Comparison between the properties of flexible polyvinyl chloride and rigid polyvinyl chloride [2], Thermal Insulation (Thermal Conductivity). Comparison between the compositions of flexible polyvinyl chloride (Top) and rigid polyvinyl chloride (Bottom) [3]. There are two main classes of PVC (Figure 2): The addition of plasticisers to PVC acts as a lubricant to the rigid crystalline polymer chains, lowering the crystallinity and yielding a much clearer and flexible plastic material. This polymerisation reaction proceeds by a free-radical mechanism. PVC is Cheap & readily available. It's currently ranked as the third most widely used plastic in the world (behind polyethylene and polypropylene). Construction: Polyvinyl Chloride is strong, light in weight, and durable. Polyester blends combine the excellent processing characteristics of PVC with the superior physical properties of polyesters, increasing abrasion resistance, tensile strength and tear resistance. It is a naturally white and very brittle (prior to the additions of plasticizers) plastic. Polyvinyl chloride (or vinyl) has stable physical properties, and excellent transparency. This number, however, continues to increase as it looks to replace traditional materials such as wood, metal, concrete and ceramics in a variety of applications. It can also be easily reprocessed using heat. Rigid PVC. 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. [Online]. Chlorinated polyvinyl chloride (CPVC) is manufactured by chlorinating the PVC product, typically increasing its chlorine content from 56% to 66% [2]. Pure PVC is white in color. Register for freeForgot Password ? Little or no maintenance is requires. PVC, in full polyvinyl chloride, a synthetic resin made from the polymerization of vinyl chloride. Its good impact strength and weatherproof attributes make it ideal for construction products. It is a naturally white and very brittle (prior to the additions of plasticizers) plastic. This is the PVC from which pipes are made, and PVC pipe is everywhere. Polyvinyl chloride is a white, rigid, quite brittle, solid. PVC (polyvinyl chloride) is a thermoplastic material that can be melted repeatedly at certain temperatures and will harden upon cooling. Rigid PVC (Polyvinyl Chloride) Unmodified polyvinylchloride is a very rigid thermoplastic. A frequent method of processing PVC involves the suspension of solid particles of the polymer in an appropriate plasticizer. Some of the key suppliers of PVC are: No Account yet? Compare Products: Select up to 4 products. What is Polyvinyl Chloride (PVC), and What is it Used For? It is a naturally white and very brittle (prior to the additions of plasticizers) plastic. 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 | H2C=CHCl or (C2H3Cl)n or C2H3Cl | CID 6338 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. [Online]. How to process it? Under ambient conditions, vinyl chloride is a colourless, flammable gas with a slightly sweet odour. It is the world’s third largest thermoplastic material by volume after polyethylene and polypropylene.

On the other hand, without the addition of these plasticisers, PVC remains a rigid, stiff material with high resistance to impact, weather, chemicals and corrosive environments. It is economical and highly resistant to chemicals. Polyvinyl chloride is most widely known for the rigid PVC pipe used in plumbing and water infrastructure systems. The equipment necessary for such a process is typically very expensive.
