Applications of HDPE Injection Molding

HDPE is a thermoplastic polymer known for its extreme durability and rigidity. It is highly resistant to moisture, impact, and chemicals, and has a high tensile strength. HDPE has a mass density range of 0.935-0.96 g/cm³, a shrinkage range of 0.025-0.035 in/in, opaque clarity, and an estimated 2.5-3.5 tonnage per square inch. Its durability, strength, and low moisture absorption make HDPE a highly versatile material, with common applications including but not limited to:

Food and beverage handling
Industrial packaging
Cases, totes, and shipping containers
Plastic bottles
Household and consumer products
