LDPE vs HDPE: Properties Production and Applications - Matmatch . LDPE has high ductility but low tensile strength, which is evident in the real world by its propensity to stretch when strained. Due to its relative ease of manufacture, availability of raw feedstock and the enormous scale on which it is produced, LDPE is a very inexpensive plastic. Michael has worked for an aerospace firm where he was in charge of rocket propellant formulation and is now a college instructor. High density polyethylene (HDPE) piping systems have been used for municipal and industrial water applications for over 50 years. Lower thickness (gauge) films can be blown compared to LDPE, with better environmental stress cracking resistance compared to LDPE. ♦ Products made from LDPE can be reused. The lower tensile strength and increased ductility are due to the strong intermolecular forces (d-I-d attraction is less). Linear Low-Density Polyethylene (LLDPE) is very similar to LDPE, but offers added advantages. See what the main advantages of the material are below. Advantages Has higher tensile strength than LDPE. LDPE (Low Density Polyethylene): LDPE has the most extensive branching compared to other polyolefins. Within PPI's Building & Construction Division, HDPE pipes are used for ground source geothermal applications, also known as earth energy or geoexchange systems. Polyethylene is limited by a rather low temperature capability (200-250 F) but is manufactured in billions of pounds per year. If you dump plastic in a small portion of soil then even a certain period of time, the plastic would remain unchanged in the soil.
