Polymer was first used by a chemist named Renault in 1835, and the first commercial application of polymer materials began in 1834 with the discovery of rubber, but the first synthetic plastic, cellulose nitrate, was discovered in 1862 and entered the market in 1868. Nylon became popular in 1938, polyethylene in 1942, polypropylene in 1957, polybutylene in 1974, and liquid crystal polymers for the manufacture of electronic components in 1985.<\/p>

Polymers are divided into three types: natural, modified natural, and synthetic polymers. The first modern industrial plastics became popular about 100 years ago, but in recent decades there has been an increasing growth and diversification in the industries. About 60 very important polymers have been introduced to the market so far, and their derivatives number more than 2,000 (including various grades of polyethylene pipe) and are still increasing.<\/p>

Polyethylene<\/h2>

Polyethylene or polyethene is one of the simplest and cheapest polymers. Polyethylene is a waxy, inert solid. It is obtained from the polymerization of ethylene and is abbreviated as PE. The ethylene molecule has a C=C double bond. In the polymerization process, the double bond of each monomer is broken and a single bond is formed between the carbon atoms of the monomers, and the resulting product is a macromolecule.<\/p>

Different grades of polyethylene pipe<\/h3>

In general, the advantages of using PE100 materials compared to other types can be summarized as follows:<\/p>

\u2013 Better processability, higher output and reduced production costs<\/p>

  • Better flexibility for coiling, pipe maintenance and installation ISO 13469<\/li>
  • Higher resistance to slow crack growth and high product safety factor (SCG test)<\/li>
  • Higher resistance to rapid crack growth (RCP) test ISO13469, Version 1996<\/li>
  • Higher hydrostatic resistance of PE100 compared to PE 80 (test according to ISO 1167 standard)<\/li><\/ul>

    Polyethylene raw materials for production<\/span><\/strong><\/h3>

    Polyethylene raw materials for the production of polyethylene pipes are produced by petrochemical companies in two forms: white (natural) and black (black). Each of these materials is produced for a specific purpose, but black materials are more suitable for polyethylene pipes that are to be used for sensitive and high-pressure applications.<\/p>

    White materials will also be of good quality if mixed with masterbatch in a proportionate and standard manner using modern and automatic machines, which depends entirely on the production line equipment, and this is done by a device called gravimetric, which is installed before the extruder hopper. Until recently, black polyethylene materials were not produced in Iran and were entirely imported, and Nem Barsha Hegmatan used all of Boruj polyethylene materials for its products, and until recently, domestic petrochemicals, including Shazand Petrochemical, joined the group of black material producers by providing and producing black polyethylene materials with the technical code CRP100, and Nem Barsha Hegmatan uses Shazand Petrochemical’s CRP100 black materials in the production of its products, at the request of customers and employers and taking into account the needs of the project.<\/p>

    Iranian petrochemicals producing polyethylene White polyethylene materials have long been produced in domestic petrochemicals, including Amirkabir Petrochemical, Maroon, Jam, and … and these three petrochemicals mentioned are among the top producers of white polyethylene materials and the properties of their polyethylene materials are suitable. Hegmethane Dehumidification, relying on the technical knowledge of its personnel and having modern production lines equipped with gravimetric equipment, produces white polyethylene materials in accordance with customer requests.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
