Low-density polyethylene
…LDPE is a thermoplastic. PEs are often classified by their densities. LDPE has more branching (on about 2% of the carbon atoms) than HDPE, so its intermolecular forces (instantaneous-dipole induced-dipole attraction) are weaker, its tensile strength is lower, and its resilience is higher…
