Marlex® 9515H High-Density Polyethylene (HDPE)

Oil bottles in garage

Marlex® 9515H high-density polyethylene (HDPE) is a blow molding grade engineered for rigid container and large-part applications that require high durability, chemical resistance and dependable processing performance. It offers a strong balance of stiffness, impact toughness, and environmental stress crack resistance, making it well suited for household and industrial chemical containers as well as larger industrial blow molded parts.

Designed to perform consistently in demanding extrusion blow molding environments, Marlex® 9515H PE supports stable parison formation, uniform wall distribution and reliable container geometry. Its mechanical profile enables manufacturers to produce containers and large molded parts that maintain integrity throughout filling, handling, transportation and end use.

Produced using CPChem’s proprietary MarTECH® loop slurry process and advanced catalyst technologies, Marlex® HDPE resins deliver uniform molecular structure, predictable processing behavior and dependable performance across blow molding platforms.
