Key Characteristics of Marlex® 7104 LLDPE  

Engineered for sheet extrusion and geomembrane applications, Marlex® 7104 LLDPE is a high-molecular-weight ethylene-hexene copolymer that delivers the stress crack resistance, melt strength, and processability that converters and geomembrane manufacturers require for demanding flat-die and large-format applications.  

Key characteristics include:

  • Outstanding ESCR: Resists environmental stress cracking under demanding service conditions, including long-term exposure in containment and barrier applications  
  • Good Melt Strength: Maintains stable extrusion behavior for consistent gauge control across heavy-gauge sheet and geomembrane production
  • Excellent Flexibility: Delivers the conformability and durability required for installed sheet and geomembrane applications across variable terrain and substrates
  • Good Processability: Runs reliably on flat-die and round-die extrusion equipment with predictable melt behavior and gauge consistency
  • Good Gloss: Produces sheet surfaces with the visual quality required for finished and coextruded sheet products
  • High Coefficient of Friction Values: Provides surface friction characteristics that support stable handling, stacking, and installation in containment applications

 

These LLDPE resin properties make Marlex® 7104 ideal for sheet extrusion and select geomembrane applications.  

LLDPE Resin for Sheet Extrusion and Geomembrane Applications

Depending on the grade, Marlex® LLDPE resins are used across flexible and semi-rigid processing methods. Marlex® 7104 LLDPE is optimized for sheet extrusion and geomembrane applications that require outstanding stress crack resistance, melt strength, and processability.
