High-density polyethylene



  High-density polyethylene (HDPE) is a kilograms of petroleum (in terms of energy and raw materials) to make one kilogram of HDPE.

Properties

HDPE has little Ziegler-Natta catalysts) and reaction conditions.

Applications

HDPE is resistant to many different solvents and has a wide variety of applications, including:

  • Containers
    • Tupperware
    • Laundry detergent bottles
    • Milk jugs
    • Fuel tanks for vehicles
  • Plastic bags
  • Containment of certain chemicals
  • Chemical-resistant piping systems
  • Heat-resistant fireworks display mortars
  • Geothermal heat transfer piping systems
  • Natural gas distribution pipe systems
  • Water pipes, for domestic water supply.
  • Coax cable inner insulators (dielectric insulating spacer)
  • Root Barrier
  • Steel Pipelines.
  • Snowboard rails/ boxes.
  • Bottles, suitable for use as refillable bottles.
  • enabled manufacture of the modern hula hoop

HDPE is also used for cell liners in subtitle D sanitary landfills, wherein large sheets of HDPE are either solid waste.

One of the largest uses for HDPE is wood plastic composites, with recycled polymers leading the way.

HDPE is also widely used in the fireworks community. In tubes of varying length (depending on the size of the ordnance), HDPE is used as a replacement for the supplied cardboard mortar tubes for two primary reasons: One, it is much safer than the supplied cardboard tubes because, if a shell were to malfunction and explode inside (flower pot) an HDPE tube, the tube will not shatter. Two, they are reusable allowing designers to create multiple shot mortar racks. Pyrotechnicians discourage the use of x-rays.
