WebJan 16, 2024 · High density polyethylene (HDPE). HDPE offers greater rigidity and durability than LDPE. It is available in translucent to opaque variation and displays excellent chemical resistance. Products made … WebLDPE is a very flexible and tough polyethylene. Compared to HDPE, it has a higher degree of short and long side-chain branching which results in lower density and crystallinity as well as in greater flexibility and toughness. However, LDPE has a significantly lower tensile strength, heat deflection temperature and melting point than HDPE.
