HDPE>>Injection Moulding
It is a thermoplastic with high crystallinity (80-90%), high density (0.94-0.97 g/cm³), excellent rigidity (tensile strength 25-35 MPa), and wear resistance. Its physical properties include a medium melt index (5-20 g/10min, 190°C/2.16kg), low shrinkage (1.5-4%), and good low-temperature impact resistance (remains tough at -40°C); its chemical properties include resistance to acids, alkalis, alcohols, and oils, but it is not resistant to strong oxidants (such as concentrated nitric acid) and high-temperature aromatic solvents (soluble in toluene at >60°C).

Injection moulding high-density polyethylene (HDPE) is widely used in injection molded products due to its high rigidity, impact resistance, and excellent processing fluidity. These products include daily necessities (such as storage boxes and trash cans), industrial components (such as pallets and gears), food containers (such as baby bottles and food storage containers), and automotive parts (such as fuel tank caps and interior trims).
