HDPE Material Plastic Part





High strength-to-density ratio, excellent chemical resistance, low moisture absorption, and good impact resistance.


Vulnerability to stress cracking under certain conditions, limited resistance to high temperatures, and poor resistance to UV radiation.

Common Application

Packaging containers, pipes for water and gas distribution, geomembranes for environmental containment, toys, bottles, and household goods.

Yes, HDPE is recyclable. It is one of the most widely recycled plastics globally due to its high demand and versatile applications in various industries.
HDPE is often preferred for food packaging because it is inert and does not react with food substances, ensuring the safety and integrity of the packaged products. Its resistance to chemicals and moisture also helps in preserving the quality of food items.
HDPE (High-Density Polyethylene) is stronger and more rigid than LDPE (Low-Density Polyethylene) due to its denser structure. However, UHMWPE (Ultra-High-Molecular-Weight Polyethylene) surpasses both in wear resistance and toughness, making it ideal for demanding applications. While HDPE is versatile and cost-effective, UHMWPE offers superior durability in specialized uses.
