RFQ Details

High-Density PolyEthylene (HDPE) or PolyEthylene High-Density (PEHD) 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.

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 for short periods, 110 C /230 continuously). High-density polyethylene, unlike polypropylene, cannot withstand normally-required autoclaving conditions. The lack of branching is ensured by an appropriate choice of catalyst (*****, Ziegler-Natta catalysts) and reaction conditions

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

Containers
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
ballistic plates
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 homogeneous 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 Pyrotechnics trade. HDPE mortars are preferred to steel or PVC tubes because they are more durable and more importantly they are much safer compared to steel or PVC. If a shell or salute were to malfunction (flowerpot) in the mortar HDPE tends to rip and tear instead of shattering into sharp pieces which can kill or maim onlookers. PVC and steel are particularly prone to this and their use is avoided where possible
