High Density Polyethylene (HDPE)

High Density Polyethylene is a petroleum-based thermoplastic that is wear resistant and can have very high elongation before breaking. It is generally chemically resistant and can withstand rather high temperatures (120° Celsius for short periods).

Common Uses:

• Beverage Industry: Caps and closures, milk jugs, refillable bottles.
• Consumer Products: Laundry detergent bottles, folding tables, folding chairs, modern hula hoops.
• Sporting industry: Portable basketball system bases, snowboard rails and boxes.
• Commercial uses: Fuel tanks for vehicles, plastic lumber, storage sheds, containment of certain chemicals, corrosion protection for steel pipelines, ballistic plates.
• Pyrotechnics Trade: HDPE mortars are preferred to steel because they are more durable and much safer.
