Polyethylene is a flexible polymer with a few remarkable properties. First and foremost, it is chemically resistant to a wide range of acids, alkalis, and solvents. Second, polyethylene is a good material for applications where less friction is desired because it has a low coefficient of friction. Thirdly, it has high electrical protection properties, making it broadly utilized in electrical and electronic applications. Additionally, polyethylene is suitable for a wide range of applications in the construction, automotive, consumer goods, packaging, and construction industries due to its low weight, long lifespan, and high impact strength. Finally, it is generally non-toxic and resistant to moisture, making it suitable for use in medical and food packaging.
Polyethylene is capable of being moulded, extruded and cast into many various shapes. It is often used in construction as it is cheap and can be shaped or moulded easily, this is why it is appropriated to be used for the jobs such as guttering. Polyethylene is a hard, stiff, strong and a dimensionally stable material that absorbs very little water. It has good gas barrier properties and good chemical resistance against acids, greases and oils. It can be highly transparent and colourless but thicker sections are usually opaque and off-white. Polyethylene also has good self extinguishing properties and resistance against ultra violet.

The specific properties of polyethylene can vary depending on its molecular weight, branching, and crystallinity.
Permanantely Lubricated High Density Polyethylene Pipes.
High-density polyethylene (HDPE) is one of the most commonly used plastics in the United States
Diamond is the hardest mineral known, so industries employ diamonds to enhance cutting and precision tools.
44W is the Canadian version of America's A36. 44W is also listed as CSA-G40.21. Mechanical Properties 44W/300W:Tensile: 65 to 85 ksiYield: 44 ksi minElongation: 20% min in 8" 23% min in 2" Mechanical Properties A36:Tensile: 58 to 80 ksiYield: 36 ksi minElongation: 18% min in 8" 21% min in 2" (for plates wider than 24")
Gemstones are valued for their brilliance, colour and hardness. They are used in industry in drill bits, especially for things like drilling wells, and in abrasives.
Polyethylene glycol is most commonly found in skin cremes and other beauty products. It is also found in lotions as it has many anti-aging properties.

Polyethylene Which is stronger Polyethylene or dyneema?

ethane is a precursor to ethylene which is polymerized to form polyethylene
Polyethylene terephthalate is made from terephthalic acid and ethylene glycol. You can modify the plastic properties by adding another glycol such as cyclohexane dimethanol in place of ethylene glycol. The properties of the plastic will be different due to the difference in size in the molecules. The polymer melting temperature will be lower since the modification of the backbone with a different sized molecule interferes with the structure of the polymer.
PVC in its native form is brittle and hard, adding other compounds called plasticizers makes PVC softer. Polyethylene's properties depend on the type. LDPE not as strong as HDPE due to irregular packing of polymer chains
Polyethylene is a plastic, not metal. In fact, polyethylene is the most common plastic now-a-days.
PEX is produced with crosslinked polyethylene. Crosslinking is obtained through a chemical process that increases the bonds between macromolecules to form a more complex structure than the normal polyethylene. Due to the crosslinking, the polyethylene's performance is greatly enhanced still maintaining the excellent properties of thermoplastics. for more details you may visit on this link : http://www.ardipex.com/pex-pipes.php
