PVC stands for polyvinyl chloride, which is a chlorine and ethylene compound used to make an odorless, solid plastic. PVC is a versatile plastic that can be used to make hundreds of products. In its rigid form, it is found in pipes, siding and windows.
Vinyl Chloride Monomer (VCM) Production. Vinyl Chloride Monomer (VCM) is the key material from which PVC is made. VCM is a gas with a molecular weight of 62.5 and boiling point of -13.9°C, and hence has a high vapour pressure at ambient temperature.
PVC polymer is a fine white powder, or resin, known as vinyl resin. This resin is treated with various additives and modifiers to make the two main types of vinyl. PVC : Rigid or Flexible--Most Versatile! PVC may be manufactured to be either rigid or flexible. Rigid PVC is used to make construction materials such as home siding and pipes.
Vinyl Chloride Monomer (VCM) is a colorless, flammable gas at room temperature. At concentrations of about 3.6 percent VCM in air, VCM can be an explosion hazard.
Vinyl chloride or chloroethene, the monomer of which PVC is made, is a simple molecule: just a pair of double-bonded carbons, one attached to two hydrogen atoms, the other to a hydrogen and a chlorine. This toxic, carcinogenic and highly flammable liquid has little value in its own right.
Polyvinyl chloride (also called vinyl or simply PVC) is a versatile thermoplastic material that is used in the production of hundreds of products that consumers encounter in everyday life and many more that are encountered less frequently but are nevertheless very important in construction, electronics, healthcare, and other applications.
Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene (vinyl chloride) monomer. This polymerisation reaction proceeds by a free-radical mechanism. Polyvinyl chloride is a white, rigid, quite brittle, solid.
Economical, versatile polyvinyl chloride (PVC, or vinyl) is used in a variety of applications in the building and construction, health care, electronics, automobile and other sectors, in products ranging from piping and siding, blood bags and tubing, to wire and cable insulation, windshield system components and more.
PVC is synthesized from vinyl chloride, C 2 H 3 Cl. The structures of the molecules are shown below. (b) The boiling point of liquid propene (226 K) is lower than the boiling point of liquid vinyl chloride (260 K). Account for this difference in terms of the types and strengths of intermolecular forces present in each liquid.
Calculations show that, in particular, the decomposition of the PVC monomer to yield HCl + C + CH 4 + H 2 is accompanied by significant (80 kJ/mol) heat release.
Polyvinyl Chloride (PVC) Home > Polymers > Polyvinyl Chloride (PVC) A major thermoplastic material with a very wide variety of applications, the essential materials for polyvinyl chloride are derived from oil and salt.
The starting material for many two-carbon compounds (including PVC) Crude oil, petroleum, or natural gas are used to obtain ethylene industrially. During a process called 'cracking', petroleum is passed through high heat and pressure, as a result of which the petroleum is broken down into ethylene, butadiene, propylene, and other by-products.
Vinyl is also used in gramophone records, and that is why we use the term vinyl records to refer to them. PVC can be used for tons of other applications from industrial ware and widely used in the healthcare sector, to car spare parts, toys factory, food packaging, raingear, etc.
