Polyethylene

The New “IT” Product


Polyethylene1
Polyethylene

  • Polyethylene is a commonly used polymer, is in high demand, and is easy to mass produce.

  • Multiple different types can be produced, including UHMWPE, ULMWPE, HMWPE, HDPE, HDXLPE, XLPE, MDPE, LLDPE, LDPE, and VLDPE.

  • Cost effective to produce, raw materials are easy to procure, and the equipment to produce it is very cheap.


Polyethylene2
Polyethylene

  • Melts between 100 and 130 °C.

  • Will not dissolve and resist’s chemicals due to it’s crystallinity.

  • Can be heat formed, holds shape after it cools

  • Lightweight yet able to hold many times it’s weight.


Manufacture
Manufacture

  • Polyethylene is a long polymer chain formed of ethylene monomers.

  • It is made by use of a fluidized bed reactor using petroleum hydrocarbons and a catalyst to facilitate it’s reaction to create polyethylene.

  • Raw materials are crude oil and natural gas.


Fluidized bed reactor
Fluidized Bed Reactor

  • Reactor designed to carry out a variety of multiphase chemical reactions.

  • Uses gas distribution and flow principles to allow liquids to react to form solids which are then taken out of the reactor while more raw materials are added

  • Works at low pressure and medium temperature.


Profit
Profit

  • Producing polyethylene gives low cost to production ratio.

  • Polyethylene can be sold to companies all over the world to make bags, containers, and personal protective clothing, as well as machinery parts and equipment.

  • Fully recyclable.


Job careers
Job & Careers

  • Factory managers

  • Oil sand worker/Off shore drillers

  • Car manufactures


Pros

  • Lightweight and tough, resistant to most chemicals.

  • Interregnal to modern society.

  • Used in majority of modern day equipment and facilities


Polyethylene cons
Polyethylene Cons

  • Made of non-renewable limited resources, mainly gas and oil.

  • Takes hundreds of years to degrade in the environment.

  • Most times it is not disposed of properly, causing it to enter the environment and cause problems.


Cons

  • Environmentally damaging to produce.

  • Raw materials are extracted using environmentally damaging methods, including offshore drilling and the Tar Sands.

  • When burned, polyethylene releases many toxic chemicals.
