Polyethylenes:
Polyethylenes It is a polymeric material composed of individual ethylene units. Ethylenes are arranged in a chain. They form a large polymer molecule. The raw material of polyethylenes is obtained from crude oil. The most important consumer market of polyethylene , Rubber industryK and plastic. Polyethylene in commercial gradesPE63،PE80وPE100Available in the global market Used in the manufacture and production of various plastics and products.
Types of polyethylene:
The types of polyethylene that are currently produced in the industry fall into the following categoriesAre divided into:
- 1.پلی اتیلن با چگالی بالا (HDPE(
- 2.پلی اتیلن با چگالی پائین (LDPE(
- 3.پلی اتیلن سبک خطی (LLDPE(
- 4.پلی اتیلن خیلی سبک (VLDPE(
- 5.پلی اتیلن با اتصالات عرضی (XLPE(
- 6.Ethylene copolymers–Vinyllining

Application of polyethylene materials:
The types of polyethylene materials mentioned above with different commercial grades, have a special properties that causeBe suitable for producing a different product. For example, more high-density polyethylene to produce Types of pipes poly ethylene and connections and too type of Reservoirs polyEthylene to used is . In addition to these casesfrom these polymer for manufacturing type of Parts plastic, type of Bottle, Box es Transport Transportation, all kinds of food storage containers, septic tanks, packing bags, etc. are used.
Made of lightweight polyethylene (LDPE(To produce all kinds of plastic parts, all kinds PE pipe, Polymer sheets, fibers, containers and films Packaging materials, plastic bags, etc. are used. Made of medium density polyethylene for making all kinds of packaging films, Production of protective coatings for metal surfaces, pipes and fittings Used for irrigation (pressurized water supply) and …. from poly Low density linear ethylene (LLDPE) In the manufacture of coatings for electrical and telecommunication cables, all kinds of coatings and protective films Plastic parts are used.
Made of very high molecular weight polyethylene for making special parts of industrialmachines, special clothes, sturdy sports goods and Bulletproof coatings are used. This type of polyethylene has a very high strength and in some cases for the manufacture of industrial equipment Defensive is used.
Other applications of polyethylene materials can be listed as follows:
- 1.Packaging accessories, production of packaging pallets, plastics, packaging tape tapes, packaging box clamps and Plastic baskets
- 2.Automotive industry, production of some interior parts of the car room
- 3.Production of home appliances, production of bottles, production of kitchen utensils, plastic partshome appliances and toys
- 4.Production of electrical and telecommunication cables, production of cable shields, sheaths and cable insulation
- 5.Types of pipes and fittings for water and sewage networks, oil and chemicals, production of polyethylene tanks for chemical storage And production of septic tanks،Carogit pipeSpiral valve
- 6.Production of polyethylene tanks for storage of medicines and health materials and all kinds of medical plastic supplies
- 7.Manufacture of insulation and coatingsPolyethylene films as moisture insulation in greenhouses, polyethylene films in packaging materialsFood and production of building insulation
