Marlex® 9512H High-Density Polyethylene (HDPE)

Oil bottles in garage

Marlex® 9512H high-density polyethylene (HDPE) is a blow molding grade engineered for rigid packaging applications that require excellent chemical resistance, impact toughness and reliable processing consistency. It delivers a balanced combination of stiffness, durability and environmental stress crack resistance, making it well suited for oil bottles, household and industrial chemical containers, and personal care product packaging.

Designed for high‑efficiency extrusion blow molding operations, Marlex® 9512H PE supports stable parison formation, uniform wall thickness and consistent container performance. Its mechanical profile enables manufacturers to produce lightweight yet durable containers that maintain integrity through filling, transport and end use.

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