WebFeb 14, 2024 · This different manufacturing process gives HDPE a regular molecular structure (known as a crystalline structure) with closely connected polymer chains. The characteristics of HDPE A tight molecular structure gives HDPE a higher density than other types of polyethylene. WebJan 14, 2024 · HDPE’s structure is crystalline. HDPE’s formidable structure gives it a higher density than LDPE. The forces of attraction between polymer molecules are strong. LDPE’s long- and short-chain branches keep the material from packing tightly in its crystalline form. This gives it less tensile strength than HDPE, but greater ductility. conditional macro wow
