LDPE is produced by polymerizing polyethylene through a high-pressure process (approximately 1600 atm and 200°C in tubular reactors). Compared to HDPE, LDPE has a highly branched molecular structure, resulting in lower crystallinity. For this reason, its stiffness and mechanical strength are lower and its chemical resistance is limited. However, LDPE offers higher impact resistance. It can be used within a temperature range of -40°C to +70°C and has a density between 0.91 and 0.92 g/cm³.
