Engineered Polymer Technologies has introduced new string-reinforced LLDPE

12/23/2018

HILLSIDE, New Jersey -- To meet the growing demand for Linear Low Density Polyethylene (LLDPE) by
geomembrane fabricators and installers, EPT has announced a string-reinforced LLDPE fabric with
the specific properties required for these types of applications. LLDPE has been in increasing
demand due to its superior flexibility and better layflat versus High Density Polyethylene (HDPE). EPT
has specially formulated its LLDPE fabric for high resistance to chemicals and UV, and offers the
material with a puncture- and tear-resistant string-reinforced scrim. It is ideal for use in solid and
hazardous waste landfills, C & D landfills, mining and industrial and municipal water and wastewater
treatment. The material, sold in jet black with a matte finish on both sides is available in widths up to
10 feet, in 30, 36 and 45 mil, for easy and efficient fabrication. A unique, embossed textured finish for
improved traction will be available early next year in all thicknesses.

“There has been increasing interest in LLDPE from our customers. We are excited to introduce a high
quality LLDPE composite membrane that combines the flexibility, chemical properties, puncture and
tear strength needed for demanding geomembrane applications,” stated Mike Satz, president of
Engineered Polymer Technologies (EPT). “We are confident this LLDPE membrane will strengthen our
portfolio of successful US made polymer fabrics and films, and meet the requirements of fabricators
and installers,” added Satz.

Both HDPE and LLDPE are polyolefins, and have excellent chemical resistance properties, making
them common choices for both primary and secondary containment. However, unlike HDPE, LLDPE is
flexible enough to be fabricated ahead of time, welded and tested on a dry floor under controlled
conditions. The advantages of this process include accelerated and more consistent welding, greater
peel adhesion and bonded seam sheer values, and reduced construction quality assurance (CQA)
expenses.
