Polyvinyl chloride is a thermoplastic material which has a wide range of applications in the industry. The formation of the PVC is very simple and takes place with the help of a process called polymerisation. In the polymerisation process Cheap Air Vapormax Online , the monomer of the basic unit is linked together in chain to form polymeric chains or what we call polymer. These polymers are macromolecules and are formed by the linking of the monomer compounds.

PVC particularly is made from the monomer vinyl chloride when it undergoes a process called polymerisation. VCM or the vinyl chloride monomer is the main raw material for the manufacturing if the PVC. Though it exists in the form of gas as the ambient temperatures, it is generally stored in the liquid state. Ethylene and chlorine are the compounds that form the basic constituents in the formation of the monomer VCM, vinyl chloride monomer. This monomer is polymerised to form the PVC resin which can then be formulated in the needed PVC compound by the addition of the appropriate additives.


Some important characteristics of Poly Vinyl Chloride


Chemical formula of vinyl chloride: C2H3Cl


Chemical formula of PVC: (C2H3Cl)n


Tensile strength: 2.60Nmm2


Coefficient of thermal expansion: 80*10-6


Melting point: 212 degree centigrade


Density: 1.38gcm3


Glass transition temperature: 81 degree centigrade


Impact strength: 2-4.5 Kjm2


Maximum continued use temperature: 60 degree centigrade


PVC is a versatile polymer which can be put be to various uses. Also, PVC is compatible with other additives used in the industry.


Poly vinyl chloride is the most renowned plastic used all over the world. The demand of PVC has been growing exponentially in the industries, especially in the developing countries.

Production of the PVC resin is dependent on the use of crude oil and chlorine in large quantities. The common manufacturing processes are listed below:


鈥?Suspension method: Suspension grade PVC is the most widely used PVC in the industry. It is manufactured by suspending the droplets of vinyl chloride in the water. Particle size of the produces resin ranges from 50-250 microns.


鈥?Emulsion method: Paste grade resin is produced from this method of polymerisation. The particle size of the paste grade resin is very fine and this Emulsion PVC resin is more costly as compared to the suspension grade PVC.


鈥?Bulk polymerisation: This method of polymerisation gives the purest form of PVC resin as no suspension agents and emulsifiers are used in the manufacturing process.


Applications of poly vinyl chloride (PVC)


PVC resin is a raw material and it can be further used to make various finished products of our daily use. The additives added to the PVC resin determines the properties of the final products beinf manufactured.


Some of the important uses of the PVC resin are:


鈥?It is used in the construction activities and imparts strength to the materials.


鈥?It is also used to make medical devices.


鈥?Manufacturing of pipes involves the use of PVC resin.


鈥?PVC resin is also used in the manufacturing of the toys for the children.
