LLDPE is a low linear density polyethylene liner produced with virgin resin. Americover’s LLDPE contains no additives, fillers, extenders or plasticizers which can migrate to the surface causing premature aging. This liner contains approximately 97.5% polymer and 2.5% carbon black, anti-oxidants and heat stabilizers. LLDPE geomembrane liners are available in mil thicknesses ranging from 6-40 mil. LLDPE is custom fabricated to size and specifications.
