Synonym: polyethylene, the High-density Polyethylene, Polyethylene high-density, PEHD
Chemical Structure:
.Polyethylene is produced from ethylene gas through adding substances can capture a polymer under pressure of various sizes, with sizes ranging from low molecular weight polymer. (the water it or beauty).(the solid elastic)
.Physical properties:
.HDPE has a chemical structure that is branch branch (branching) less the attraction between the molecules of พอลิเมอร์ค่อนข้าง high strength. When the higher density, hardness and toughness are increased, but when the density decreased.Heat resistant, chemical resistant, but much better by heat (high temperature resistant to 110 ° C and resistance to high temperature, high to 120 ° C in short-term. ) but can not bear high temperature in the pot and steam (Autoclave) as the plastic, PP (PolypropyleneThe number 5) and chemical resistance than LDPE (Low-density polyethylene, symbols, numbers 4) weather resistance well enough to มควร. But the weather can be permeable
.HDPE has opaque white, translucent, slide it in, toughness and elasticity, no smell, ไม่มีรส density lower than water will float. Can be mixed with various colors. Background:
.Polyethylene (Polyethylene or Polythene) was found in 1933 by Reginald Gibson and Eric Fawcett of company Imperial Chemical. Industries (ICI) in England, this type of material 2 forms LDPE HDPE by LDPE and used to produce the film and วัสดุสำหรับ packaging The HDPE.Use of packaging production, water and automotive accessories
.HDPE material type Polyethylene Thermoplastic (Thermoplastic. Is a plastic that can bring back the melt using the new). The petroleum industry. A plastic that has been the symbol 2 number, which means Resin Identification Code 2.(recycled)
.In 1945 Earl Tupper of company DuPont game systems. Notice that the polyethylene is a synthetic polymer with toughness, durable, can be used to cast in the mold to size. Shape and color combinations have different colors, with production starting glass plastic.The popular because the light weight, color use, and later produced a container with a cover. Which is the source of the food container has been popular with housewives in those days, in the name of Tupperware (Tupperware apertium).
.Usage:
.HDPE chemical resistant and solvent species. Flexible to strong ironic broken easy can be utilized in various tasks, especially the manufacture of container prepared from blow from the mold. (blow molding).River type, removed from the mold, easily produced from HDPE container such as bottles, milk bottles, oil tank washing liquid in the motor. Contractor table - folding chair, plastic bags, etc. also, HDPEExamples of products made from HDPE
- bottle drinking water bottle milk ice tray
- containers, boxes, jars of food packing bottle and vitamin C
-. Reagent bottle, a bottle of liquid soap (pump bottle) bottle washing liquid tin powder
.Crates and boxes - packing bags of
