High-density polyethylene Totally Explained

Everything about Hdpe totally explained

High-density polyethylene (HDPE) is a polyethylene thermoplastic made from petroleum. It takes 1.75 kilograms of petroleum (in terms of energy and raw materials) to make one kilogram of HDPE.

Properties

HDPE has little branching, giving it stronger intermolecular forces and tensile strength than lower-density polyethylene. It is also harder and more opaque and can withstand somewhat higher temperatures (120 °C for short periods, 110 °C continuously). High-density polyethylene, unlike polypropylene, can't withstand normally-required autoclaving conditions. The lack of branching is ensured by an appropriate choice of catalyst (for example, 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
folding tables
folding chairs
storage sheds
Portable basketball system bases
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
Corrosion Protection for Steel Pipelines.
Tyvek
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 extrusion or wedge welded to form a chemical-resistant barrier, with the intention of preventing the pollution of soil and groundwater by the liquid constituents of solid waste.
One of the largest uses for HDPE is wood plastic composites and composite wood, 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's much safer than the supplied cardboard tubes because, if a shell were to malfunction and explode inside (flower pot) an HDPE tube, the tube won't shatter. Two, they're reusable allowing designers to create multiple shot mortar racks. Pyrotechnicians discourage the use of PVC tubing in mortar tubes because it tends to shatter, sending shards of plastic at possible spectators, and won't show up in x-rays.
