Synonyms: polyethylene, High-density Polyethylene, Polyethylene high-density, PEHD chemical structures. : polyethylene production from gas ethylene through the addition of substances that can form a polymer under pressure of various sizes made polymer that size since. low molecular weight (A viscous oil or wax) to a high molecular weight. (Solid, flexible) Physical Properties: HDPE has a chemical structure that is a branch (branching), so there is less attraction between molecules of the polymer is relatively high. Strength When a higher density, hardness and toughness will increase. But when the density decreases Will make the transition easier. Heat was not much. However, good chemical resistance By heat (Withstand temperatures up to 110 ° C and withstand temperatures up to 120 ° C in brief), but can not withstand high temperatures in the autoclave steam (Autoclave) as plastics PP (Polypropylene, the No. 5) and withstand. Chemicals over LDPE (Low-density polyethylene, the No. 4) resistant to weather reasonably well. However, air can penetrate opaque HDPE is a translucent slip it in. Toughness and flexibility, no smell, no taste, has a lower density than water, so it floats on water. You can mix different colors for Background: polyethylene (Polyethylene or Polythene) was discovered in 1933 by Reginald Gibson and Eric Fawcett of company Imperial Chemical Industries (ICI) in England. There are two forms of this material is LDPE and HDPE by using LDPE film and HDPE materials for the packaging is very strong. The manufacture, packaging, water pipes and automotive HDPE. A material Polyethylene Thermoplastic (Thermoplastic. The molten plastic is recyclable reusable) from the petroleum industry. A plastic that has been the number two, which means Resin Identification Code 2 for easy identification of plastic for recycling to make new circular. (Recycled) in 1945 Earl Tupper of DuPont® company noted that the polyethylene is a synthetic polymer that is durable and can be cast in a mold to size, shape and color to a different color. It began with the production of plastic cups and bowls, which are popular because they are lightweight, colorful and subsequently produce containers with lids. Which is the source of food containers that have been popular with women in those days. In the name of Tupperware. (Tupperware®) that use: HDPE resistant to chemicals and many solvents. Flexible strength concussion Not easy rupture Can be used in a variety of jobs, especially manufacturing containers prepared by blowing by molding (blow molding) due to shrinkage in the mold very well. No mold It is easily removed from the mold. Production of HDPE containers such as bottles, milk bottles, detergent. Tank in automotive, plumbing table - chairs, folding plastic bags, etc. Also, HDPE is used for lining the landfill waste to prevent leakage of chemicals into the soil and bodies of water samples are made. from HDPE - water bottles, milk bottles, ice tray - a container box food bowl. Transmission medicines and vitamins - bottle chemical bottle of liquid soap (pump bottles) bottle of laundry detergent, canned dough - crates and boxes, packing bags - the children - insulation - tables, chairs Synonyms: polyethylene.
