HBM 5520 is a high-density polyethylene (HDPE) with medium molecular weight, developed using 1-hexene as a co-monomer. This grade offers a well-balanced combination of toughness, excellent environmental stress crack resistance (ESCR), strong mechanical properties, and smooth processability. HBM 5520 is ideally suited for general-purpose blow molding applications, providing reliable performance across a wide range of end uses. It is manufactured under Basell’s licensed technology to ensure consistent quality and durability.
