Polyvinyl chloride is the same as PVC or Vinyl. It is one of the most expensive plastics which are commonly used in the modern society. This plastic is used to make different materials and items such as water bottles, credit cards, toys, window frames, pipes and many more. Polyvinyl chloride was the first plastic product to be untested in the year 1913. This has been challenged by the fact that it is manufactured using toxic materials and it causes tremendous environmental pollution.
Polyvinyl chloride has the resin code of PVC. There are many companies which manufacture different brands of PVC, and they give their brands different names. Such names given to PVC include: PUR whose name is Vasco® manufactured by Vista group. There is also TPE whose trade mark is Vaycron®, and it is manufactured by Ineos Company. This plastic has a low rate of water absorption, but it loses its color exceptionally fast. Finally there is PVB, whose trade mark is Vanceva®, and it is manufactured by Solutia Company. This one is a plastic which has a wear resistance, and it can be able to bear extremely high temperatures and can best suit environments which are highly corrosive.
Polyvinyl chloride is made from a wide range of raw materials, which come in different forms. Some of these raw materials include: salt which is mainly found in crystal or pellet form. There is also oil which mainly comes in bulk containers. Some plasticizers, which come in sheet forms, are also used to make PVC flexible. There is also additional of lubricants which come in bulk containers, and they are in liquid form. Colors and toners come in pellet form for use in PVC at later stages of production of manufacturing. Modifiers occur in sheet form and are added to make PVC strong. The manufacture of PVC includes various processing methods such as injection molding, extrusion, calendaring, blow molding, slush molding, rational molding among others. PVC is mainly classified as a thermoplastic resin since it can be made soft by heating. In most cases, PVC plastics melt on heating. It is worth noting that materials used in furnaces cannot be made using PVC. This is mainly because PVC is a thermoplastic and it becomes soft on heating. PVC cannot also be used to manufacture objects that carry heavy weight as PVC materials easily bend.
PVC has been used to make a variety of products and the most common one is PVC pipes. These are pipes made from a plastic which is combined with vinyl. These pipes are long lasting, and they do not get damaged easily. They also do not rust or even rot and they are durable. This makes them mainly be used in water systems, in sewerage lines in in underground electric wiring.
PVC products have a wide range of adverse environmental impacts. This is mainly due to the non-biodegradable nature of PVC products. This means that these products do not decay and they end up being environmental pollutants. Some of the raw materials used to make PVC products causes cancer, result to kidney problems and can cause reproductive disorders. Most plastic materials make the environment look unpleasant when they are wrongly disposed. Burning of PVCs results to the production of chlorofluorocarbons, which cause air pollution. The best methods to dispose PVC products is recycling, deep burying or even burning in an incinerator. Recycling can be carried out in one of the following ways: They can be re-used in their current form or the polymer can be heated at a high temperature and the resulting component can be made into other plastic products. Incineration reduces the amount of toxic gases emitted into the atmosphere since incinerators have pollution control equipment. PVC products should not be disposed in a land fill as this would create an eye sore, create a breeding site for mosquitoes and other vectors and they are unhygienic when children use them as toys.
In conclusion, PVC materials are used on everyday life and are manufactured from materials which come in different configurations. They have different brands and are used for various purposes. PVC materials are environmental pollutants if not properly disposed, but this can be prevented when proper precaution is put in to consideration.
