Most of the high-consumption polymers in the petrochemical industry include polyethylene, polyethylene terephthalate, polypropylene, polyvinyl chloride, polystyrene and acrylonitrile butadiene styrene. Polyethylene, which is mainly produced in three groups of heavy polyethylene, lightweight and linear, is the most consumable polymer in the world. The rapid growth of polyethylene terephthalate and polypropylene consumption compared to polyvinyl chloride made it the second largest copper polymer in the fourth place after polyethylene terephthalate and polypropylene. Polystyrene and acryl and nitrile butadiene styrene are also in the next steps after polyvinyl chloride.
PE
Ethylene is the lightest olefin, which is a colorless, flammable gas and almost sweet odor. Polyethylene is a polymer that is made of ethylene. Polyethylene resins have been used in countless products due to its high flexibility, good resistance to acids, bases and salts (with the exception of strong oxidizing materials) and, therefore, today the world's largest polymer production Has been allocated. At present, the global consumption of this polymer is 69 million tonnes, equivalent to 31% of the total consumption of high-consumption polymers in the world. The three main groups are polymer, heavy polyethylene, light polyethylene and linear polyethylene.
Heavy Duty Polyethylene HDPE
The compression of the molecular chain in this type of polymer increases the density and decreases its flexibility. Although this polymer has less impact resistance than light polyethylene, its resistance to chemicals is very good in fragile stresses. It is therefore used in the manufacture of various commercial products such as fuel storage containers, outdoor chairs, toys, towels, tubes, cable and wires, and so on.
LDPE-grade polyethylene
Lightweight polyethylene is low in compact density due to its low density and, consequently, its flexibility. This feature has made the product in film and sheet construction for use in transparent moldings, packing liners, covers, pressure vessels, laminates Cable and wire, and so on.
Linear polyethylene
This polymer has a lower density than light polyethylene, showing a better rigidity and tensile strength than rupture and perforation. This polymer is used for the production of packaging film, cable and wire lining, bottles and containers, toys, sheets, tubes and so on. Asia, North America and Western Europe are the world's largest polyethylene producers, respectively.
Linear polyethylene production in 2002 reached 14.9 million tons, up 5.7 percent to 19.6 million tons in 2007. The production of this polymer is projected to increase to about 26 million tons in 2012. Because of its unique characteristics, it has a higher consumption than light and heavy polyethylene. It is anticipated that by 2017, the use of this polymer will be canceled with an average annual consumption growth of 4.5% to about 34 million tonnes (34% of total polyethylene consumption). It is also anticipated that, in 2017, heavy polyethylene will account for 46 percent of the total polyethylene consumption, with 46 million tons consumed. Although apparently the polyethylene market has been saturated with light, the consumption of this polymer is projected to increase from about 17.7 million tonnes to about 20.7 million tonnes by 2017.
Polyethylene terephthalate
This soft, soft plastic, which has created a huge transformation in food storage (liquids), has been used extensively in the maintenance of carbonated beverage liquids due to high strength and high pressure tolerance over PSI 100 and resistance to carbon dioxide gas transmission. Has found it. This polymer is mainly produced in two grades of bottles and fibers. The second most popular polymer in the world.
Bottle Grade
As the name suggests, this grid is used to store carbonated carbon drinks. At present, its global consumption is 14.2 million tons, equivalent to 6.7 percent of the world's ottoman residues, and is projected to increase to around 8.26 million tons by 2017.
Fiber grade
This grade is used in the production of all kinds of textiles and clothing. It is best suited for natural cotton. At present, global fiber grit consumption is 29 million tons, accounting for 13.6 percent of the world's consumption of high-density polymers. The amount of this polymer is expected to rise to around 41.3 million tons in 2017. Dacron and Troyra, the brand of some of the more polyethylene fibers phthalate.
Polypropylene
Polypropylene is a heat-soak polymer that was first obtained in 1951 by Dr. Karl Mähnen, without notice of its importance. The significance of this polymer was discovered by its reconsideration by Julianata in 1954. Polypropylene is the third most popular polymer in the world with an annual consumption of 45.6 million tons and an allocation of 20 percent of the consumption of basic polymers. The ability to increase filler, reinforcement and other modifiers has made polypropylene a high-consumption polymer. The global production capacity of this polymer in 2002 was about 39.4 million tons, up 4.5 percent to reach 49 million tons in 2007. Global demand for polypropylene is projected to increase to 69.5 million tons by 2017.
Polypropylene in the automotive industry in the manufacture of interior decoration, butterfly, car flooring and battery box, as well as in the construction of the radio and television, components of the dishwasher, washer and tubing mixers, tubes, packaging of packaging films for food industry and production of fiber for production Carpet, back and sack are used.
