Answer:
HDPE is defined by a density of greater or equal to 0.941 g/cm3. HDPE has a low degree of branching. The mostly linear molecules pack together well, so intermolecular forces are stronger than in highly branched polymers. ... HDPE has high tensile strength.
Density: 0.88–0.96 g/cm3
Magnetic susceptibility (χ): −9.67×10−6 (HDPE, SI, 22 °C)
Chemical formula: (C2H4)n
