  1. Polyethylene The New “IT” Product

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. Job & Careers • Factory managers • Oil sand worker/Off shore drillers • Car manufactures

  8. Pros • Lightweight and tough, resistant to most chemicals. • Interregnal to modern society. • Used in majority of modern day equipment and facilities

  9. 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.

  10. 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.
