Marlex® 9708 High-Density Polyethylene (HDPE)

Multicolored Crates

Marlex® 9708 high-density polyethylene (HDPE) is an injection molding grade engineered for heavy‑duty rigid applications requiring high stiffness, toughness and dependable structural performance. It delivers a balanced combination of mechanical strength, impact resistance and chemical durability, making it well suited for crates, tote boxes and structural foam parts used in demanding handling and logistics environments.

Designed to perform reliably in thick‑section and structural applications, Marlex® 9708 PE supports consistent part geometry, dimensional stability and long service life in products exposed to repeated loading, stacking and transport. Its mechanical profile helps manufacturers produce rigid containers and components that maintain integrity throughout extended use cycles.

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