What is PE? History polyethylene, polyethylene Types and Their Benefits

خط تولید لوله های پلی اتیلن PE

Polyethylene is one of the simplest and most inexpensive polymers.
Solid polyethylene wax is disabled. This material is derived from the polymerization of ethylene and PE are briefly shown.
Molecules of ethylene (C2H4) is a C = C double strap. Each of the monomers in the polymerization process of the double bond has been broken, and instead of a simple link between the carbon atoms of the monomer is generated and product creation is one Drshtmvlkvl.

History of Polyethylene
Polyethylene was first accidentally by a German chemist "Hans Von Pechmanv" was synthesized. In 1898 he de Zvmtan heating, combine the white waxy polyethylene synthesis which later was named.
The first method of industrial synthesis of polyethylene randomly by "a Navst" and "Rynvlrgysvn" (from chemists ICI) was discovered in 1933. By heating a mixture of ethylene and benzaldehyde the scientists at high pressure, a substance found Mvmmannd. This reaction is due to the presence of impurities in the oxygenation device was used as the polymerization initiator was performed.


PE History
The word polymer is derived from the Greek (poly) means few, and (stage) means a unit or section has occurred. Error resin polymers, elastomers, and plastics also called.
I know the chemical composition of the polymer by first name Rnalt in 1835, went to work and the first commercial application of polymer materials began in 1834 with the discovery of rubber.
However, the first synthetic plastic called cellulose nitrate discovered in 1862 and released in 1868.
In 1938, nylon, polyethylene, in 1942, in 1957, polypropylene, polyester and liquid crystal polymers Bvtyln in 1974 and were established in 1985 to manufacture electronic components.
Three kinds of polymers with natural polymers, modified natural and artificially divided.
The first modern industrial plastics became popular about 100 years ago, but in recent decades a growing and diverse industry took place.
