High Density Polyethylene is a thermoplastic resin produced by the polymerization of ethylene under low-pressure conditions. It is a non-toxic, odorless, and tasteless material that appears as white powder or pellets, with a density range of 0.94-0.97 g/cm³. HDPE offers good heat resistance (service temperature up to 100°C), excellent chemical resistance, outstanding moisture barrier properties, and high mechanical strength. Its tensile strength exceeds 20 MPa, approximately twice that of Low Density Polyethylene (LDPE). This material is widely used in food packaging, dairy bottles, shopping bags, industrial containers, pipes, and other applications.
