High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylene thermoplastic made from petroleum. Known for its large strength to density ratio, HDPE is commonly used in the production of plastic bottles, corrosion-resistant piping, geomembranes, and plastic lumber. HDPE is commonly recycled, and has the number "2" as its recycling symbol.

In the industrial context, HDPE stands for high-density polyethylene, which is a type of thermoplastic polymer that is widely used in a variety of applications due to its durability, strength, and resistance to chemicals and UV radiation. Here are some examples of industries and applications where HDPE is commonly used:

1. Packaging industry: HDPE is used to make a wide range of products, including plastic bags, bottles, and containers.

2. Construction industry: HDPE is used in various construction applications, such as piping, geomembranes, and insulation.

3. Agriculture industry: HDPE is used in agricultural applications, such as irrigation piping, greenhouse film, and silage bags.

4. Automotive industry: HDPE is used in various automotive applications, such as fuel tanks, bumpers, and fenders.

Similar concepts in the industrial context include:

1. Thermoplastic polymers: HDPE is one of many types of thermoplastic polymers that are used in industrial applications, including polypropylene (PP), polyvinyl chloride (PVC), and polycarbonate (PC).

2. Packaging materials: In addition to HDPE, other materials such as polyethylene terephthalate (PET) and polystyrene (PS) are commonly used in packaging applications.

3. Construction materials: In addition to HDPE, other materials such as polyvinyl chloride (PVC) and polyurethane (PU) are commonly used in construction applications.

4. Automotive materials: In addition to HDPE, other materials such as acrylonitrile butadiene styrene (ABS) and polyamide (PA) are commonly used in automotive applications.
