Synonyms: polyethylene, High-density Polyethylene, Polyethylene high-density, PEHD chemical structures. : polyethylene produced from the gas ethylene through a process additive that allows it to capture a polymer under the pressure of various sizes made polymer size from. 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 will result in increased hardness and toughness. The lower density To make the transition easier. Heat was not much. However, good chemical resistance By heat (Resistant to 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, symbol No. 5) and withstand. chemicals than LDPE (Low-density polyethylene, the No. 4) resistant to weather reasonably well. But air permeable HDPE opaque, translucent slip it in there. Toughness and flexibility, no smell, no taste, has a lower density than water, floats in 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. This type of material has two forms: the LDPE LDPE and HDPE films and materials for the production of HDPE packaging is very strong. The production of packaging equipment, vehicles, water and HDPE. A material Polyethylene Thermoplastic (Thermoplastic. The molten plastic is recyclable reusable) from the petroleum industry. A plastic that has been the No. 2, which represents the Resin Identification Code 2 to facilitate the identification of plastics in bringing back a new round. (Recycled) in 1945 Earl Tupper of companies DuPont® 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. He began by producing plastic and glass water bowl, which is popular because it is lightweight, colorful and later use containers with a lid. This is a source of container, food has been popular with women in those days. In the name of Tupperware. (Tupperware®) that use: HDPE resistant to chemicals and solvents of various kinds. Flexible Impact Concussion Not easy to crack Can be used in a variety of jobs, especially for the production of 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. Containers such as bottles made of HDPE milk bottles, detergent. Tank in automotive, plumbing table - Chair, 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 - container boxes containing food jars. 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.
