History of Natural and Synthetic Polymers

Thus, linear PE has higher density than the branched material (density range of 0.94-0.965 g/cm3 vs 0.91-0.94 g/cm3), higher melting point (typically >125 C vs. 112 C), greater stiffness and tensile strength, greater hardness, and less permeability to gases and vapors.
