Geomembrane resin manufacturers embrace non-PFAS polymer processing aids amidst growing regulatory pressure

September 21st, 2023

High-Density Polyethylene (HDPE) geomembranes play a crucial role in various industries, from environmental containment to civil engineering projects. These geomembranes are manufactured using high molecular weight polyethylene resins, with the aid of polymer processing aids (PPAs) to enhance production efficiency. Traditionally, fluorinated polymers mixed with fluorosurfactants have been the go-to PPAs due to their ability […]

An open solicitation to work on development of a new GSI specification for EIA geomembrane

August 1st, 2022

GSI has a long history of writing specifications for geosynthetics. Like all engineered materials, geosynthetics are used in many applications and need general requirements for plans and specifications. When the NSF ceased servicing NSF #54 “Specification for Geomembranes” in 1991, The Geosynthetic Institute (GSI) was requested by its membership to continue the effort. With a […]
