Engineered Polymer Technologies introduced new string-reinforced LLDPE



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 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.
