Marlex® HHM TR-392 medium-density polyethylene (MDPE) is a high-performance ethylene-hexene copolymer engineered for demanding pipe and tubing applications requiring excellent tensile elongation, outstanding resistance to slow crack growth and very good thermal stability. Its mechanical profile supports long-term durability and flexibility in irrigation systems.
Leveraging decades of polyethylene manufacturing expertise, CPChem produces Marlex® MDPE resins using advanced catalyst systems and rigorous process controls. This approach delivers consistent molecular structure and predictable extrusion performance for long service life in MDPE piping applications.
