Marlex® 7104 Linear Low-Density Polyethylene (LLDPE)

Employees working at CPChem Cedar Bayou

Marlex® 7104 LLDPE is designed for sheet extrusion where toughness, tear resistance and cap-layer adhesion matter. It supports coextruded cap layers on HDPE structures and is applicable to geomembranes such as landfill covers and flat or round-die products.

Leveraging decades of polyethylene manufacturing expertise, CPChem produces Marlex® LLDPE resins using advanced catalyst and process technologies designed to deliver consistent molecular architecture and dependable resin quality. This foundation enables sheet extrusion and thermoforming converters to achieve predictable processing behavior, uniform sheet thickness, and reliable mechanical performance across demanding LLDPE sheet applications.
