Marlex® 9503HF High-Density Polyethylene (HDPE)

Detergent bottle

Marlex® 9503HF high-density polyethylene (HDPE) is a high‑flow blow molding grade engineered for rigid packaging applications that require excellent environmental stress crack resistance and stable processing performance. It provides a balanced combination of stiffness, toughness and chemical resistance, making it well suited for detergent bottles, household chemicals and industrial containers produced in high‑speed blow molding operations.

Designed to support efficient parison formation and uniform wall distribution, Marlex® 9503HF PE enables manufacturers to achieve consistent container geometry, reliable top‑load strength and repeatable part performance. Its high‑flow characteristics help improve productivity while maintaining durability throughout handling, filling 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.
