High Density Polyethylene (HDPE)

HDPE stands for High-Density Polyethylene. It is a type of thermoplastic polymer made from petroleum. HDPE is known for its high strength-to-density ratio, making it a versatile material used in various applications.

Key Characteristics

High Density

As the name suggests, HDPE has a high density, which gives it excellent strength and durability. This makes it suitable for applications where strength is crucial.

Chemical Resistance

HDPE is highly resistant to many chemicals, including acids and bases. This property makes it ideal for use in containers and piping systems for transporting various chemicals.

Weather Resistance

HDPE is resistant to weathering, making it suitable for outdoor applications. It doesn't degrade easily when exposed to sunlight, moisture, or extreme temperatures.


Despite its high density, HDPE is also relatively flexible. This flexibility allows it to withstand impacts and deformation without cracking or breaking.


HDPE is recyclable and can be melted down and reformed into new products, making it an environmentally friendly material.

Overall, HDPE’s combination of strength, chemical resistance, weather resistance, and recyclability makes it a highly versatile material used in various industries and applications.
