And its Future Use
Introduction
Poly vinyl chloride commonly known as premature ventricular contraction or Vinyl is the 3rd largest selling trade good plastic in the world today1. Although early accidental discoveries of polyvinyl chloride were found in the 1800s it wasnt until the 1920s when an industrial scientist named Waldo Semon at BFGoodrich commercialized the material for use as a water resistant coating for fabrics. During the 1950s the refining methods compound durability introducing its use in the building and the construction industry. irrigate pipes used in the transportation of water to homes and factories began to be make out of PVC due to the materials foe to chemical substances and corrosion. Today PVC is used in a wide variety of applications and industries both(prenominal) examples are IT (communication and electronics), transport (food packaging), textiles and construction.
Atomic structure and Properties
Below is the chemical formula for PVC that consists of Carbon, Hydrogen and Chloride.

PVC is a thermoplastic polymer meaning that is recyclable, the addition of the atomic number 17 atom allow for easier identification during automated sorting systems and with todays society be environmentally concise these become master(prenominal) properties.
Other important properties of PVC that make it a desirable polymer are its resistance to chemicals and corrosion, good electrical and thermal insulator, fire retardant (burns slowly) and has relatively good strength. Undesirable properties of PVC is that it softens at a relatively low temperature (54~80C)2 and it has a high density when compared to other polymers.

PVC Production
PVC is produced in a variety of techniques that includes rest period, emulsion, micro suspension and bulk using addition polymerization. Suspension polymerization is the well-nigh common PVC process.3 The production of PVC first starts with chlorine being extracted from salt by the process of electrolysis. The chlorine is thus reacted with ethylene...If you want to get a full essay, order it on our website: Orderessay
