Various additives and pigments are added to PVC during the processing stage, and the blend is then converted into PVC products.<br \/>\nPVC is sometimes known as \u2018Vinyl\u2019 in Europe and predominantly so in North America. In Europe, \u2018Vinyl\u2019 usually refers to certain specific flexible applications, such as flooring, decorative sheets and artificial leather.<\/p>\n<div>\n<div>\n<div>\n<div><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.pvc.org\/var\/ecvm\/storage\/images\/media\/images\/pvc_pellets_-ineos-web\/5401-1-eng-GB\/PVC_pellets_-Ineos-WEB_medium.jpg\" alt=\"PVC_pellets_(Ineos)WEB\" width=\"200\" height=\"157\" \/><\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>PVC is a thermoplastic made of 57% chlorine (derived from industrial grade salt) and 43% carbon (derived predominantly from oil \/ gas via ethylene). It is less dependent than other polymers on crude oil or natural gas, which are nonrenewable, and hence can be regarded as a natural resource saving plastic, in contrast to plastics such as PE, PP, PET and PS, which are totally dependent on oil or gas. This chlorine gives to PVC excellent fire resistance: when PVC is set on fire, the flames go out as the fire source is removed due to the material\u2019s self-extinguishing properties.<\/p>\n<p>PVC is one of the most used plastic materials in the world. At global level, demand for PVC exceeds 35 million tonnes per annum and it is in constant growth (+5% on global average), with higher growth rates in the developing countries.<\/p>\n<p>It is the most widely used polymer in building and construction applications and over 60 per cent of Western Europe\u2019s annual PVC production is used in this sector.<\/p>\n<p><strong>PVC is a more economic material<\/strong><br \/>\nPVC products make life safer, more comfortable and more pleasurable. And, because PVC has an excellent ratio of economic cost to performance, it allows people of all income levels access to these important benefits. The diversity of PVC applications challenges the imagination. In everyday life, they are all around us, from construction profiles to medical devices, from roofing membranes to credit cards, from children\u2019s toys to pipes for water and gas. Few other materials are as versatile or able to fulfil such demanding specifications. In this way, PVC facilitates creativity and innovation, making new possibilities.<\/p>\n<p><strong>PVC underpins safety<\/strong><br \/>\nWire and cables sheathed with PVC prevent potentially fatal electrical accidents. In hospitals around the world PVC medical tubing \u2013 which does not break or kink \u2013 delivers fluids and medicines to the sick. Car components which use very strong PVC can reduce the risk of any injuries being caused in case of an accident. Most PVC products are long lasting \u2013 up to and over 60 years. These applications are reliable throughout their service lives and cut down vastly on maintenance or repair. Modern cars, for example, last many years longer simply because PVC protects the underside from water and corrosion.<\/p>\n<p><strong>PVC enhances our lives<\/strong><br \/>\nFunctional performance is by no means the whole story. PVC has a distinguished role in beauty and aesthetics. In fashion, furniture and all types of indoor and outdoor accessories, PVC opens up functional and design opportunities that are both visually striking and fundamentally practical. In short, people everywhere benefit from this material. Sometimes invisible but always reliable, PVC products make the difference when it counts.<\/p>\n<p>References:<\/p>\n<p>http:\/\/www.pvc.org\/<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The thermosetting resins include phenolic resin and melamine resin, which are thermally hardened and never become soft again.
