HDPE

HDPE – High-Density Polyethylene

HDPE (High-Density Polyethylene) is a highly durable and versatile plastic known for its strength, chemical resistance, and broad range of applications. It was first synthesized in 1953 by Karl Ziegler and Erhard Holzkamp in Germany. Ziegler received the Nobel Prize in Chemistry for this invention in 1963.

Properties of HDPE

• Density: 0.93–0.97 g/cm³
• High tensile strength and rigidity
• Resistant to acids, oils, and alcohol
• Easy to machine and cut, chip-free processing
• Excellent insulator
• Performs well in cold and UV-exposed environments
• Non-toxic and fully recyclable

Uses of HDPE

• Food packaging, bottles, caps
• Plastic bags and films
• Pipes for gas, water, and sewage
• Household goods: brushes, pegs, toys
• Industrial parts, liners, seals

Special Variants

For applications that require exceptional stress and surface resistance, HDPE with extra high molecular weight (EHMW) is used.
