GPS LL Smooth- LLDPE

GPS LL Smooth is designed specifically to fulfill any containment needs.  GPS LL Smooth has been well-proven to be effective through numerous oil & gas, industrial, municipal, agricultural and decorative projects. These geomembranes conform to meet heap leaching containment requirements and tailing impoundment design criteria. GPS LL Smooth comes in  light colored LLDPE  geomembranes for reduction in surface heat and textured membranes for higher friction angle requirements. 

Linear low-density polyethylene (LLDPE) GPS LL Smooth is used for its higher flexibility compared to other liners.  With excellent elongation properties, it can mold to any pre-existing topography and is often used in buried applications. The overall flexibility of the liner also makes installation easy and reduces potential damage to the system. It also maintains high tear resistance to ensure system integrity even in hazardous conditions. GPS LL Smooth is manufactured with virgin resins to ensure superior performance.

LLDPE Common Applications:
  • Coal Ash Impoundments
  • Reserve Pits
  • Frac Pits
  • Under Rig Liners
  • Retention Ponds
  • Fresh Water Pits
  • Flowback Pits
  • Secondary Containment
  • Above ground Storage Tanks              Download Data Sheet Here

(1) Machine direction (MD) and cross machine direction (TD) average values should be on
the basis of 5 test specimens each direction.
• Break elongation is calculated using a gage length of 2.0 in at 2.0 in./min
(2) Other methods such at D 1603 (tube furnace) or D 6370 (TGA) are acceptable if an
appropriate correlation to D4218 (muffle furnace) can be established.
(3) Carbon Black dispersion (only near spherical agglomerates) for 10 different views.
• 9 in Categories 1 or 2 and 1 in Category 3
(4) The manufacturer has the option to select either one of the OIT methods listed to evaluate
the antioxidant content in the geomembrane.
(5) The condition of the test should be 20 hr. UV cycle at 75°C followed by 4 hr condensation
at 60°C.
(6) Not recommended since the high temperature of the Std-OIT test produces and
unrealistic result for some of the antioxidants in the UV samples.
(7) UV resistance is based on percent retained value regardless of the original HP-OIT value.
(8) Roll widths and lengths have a tolerance of ± 1%
