Raven Industries' Engineered Films Division (Sioux Falls, SD), an innovative manufacturer of specialty plastic film and sheeting, has announced the launch of a new flexible geomembrane product line designed to provide effective containment for the energy and environmental sectors. HydraFlex Containment Solutions is the newest addition to the Raven product line and includes several targeted geomembranes designed for specific project attributes. All HydraFlex products are available in master rolls or large, prefabricated one-piece panels of up to 8,000 lbs with a wide sealing window for ease of installation.

"The new HydraFlex family contains three distinct product lines designed to deliver targeted containment solutions," said Bart Brown, Director of Sales. "We conducted thorough market analysis through customer experiences to develop HydraFlex and found exactly what the customer needs to increase overall project value. The HydraFlex line will be key in sustainable environmental resource protection through many containment applications, and we are excited to announced these additions."

HydraFlex Ultra is the HU-Series geomembranes, which are produced with flexible, linear, low-density polyethylene resin to impart elongation and tensile and impact strength properties. HydraFlex Ultra is formulated to meet or exceed the comprehensive requirements of GRI-FM17 Standard Specification for LLDPE geomembranes. HydraFlex Ultra is recommended for use in containment applications requiring outdoor longevity, chemical resistance and durability, notably in cold-weather environments. With its flexibility, HydraFlex Ultra easily conforms to uneven surfaces, and performs well in critical applications, including fish-safe requirements for aquaculture and coal-ash impoundment capping for the solid-waste sector.

HydraFlex Pro HP-Series geomembranes are co-extruded from linear, low-density polyethylene and are developed for applications requiring enhanced flexibility along with a combination of high tensile strength and impact resistance. HydraFlex Pro is engineered with ultra-low-modulus characteristics to resist pinholes and flex-cracks during installation. These elements are critical for the pliability necessary in reliable above-ground tank-lining systems, as well as in earthen pit and pond linings. The additive package in HydraFlex Pro includes fine, partial carbon black on one side to protect from UV radiation and thermal degradation. The gray color on the opposite side minimizes thermal expansion while providing cooler surface characteristics. Contrasting colors also provide a vital function for ease of damage detection during the installation process.

HydraFlex H-Series materials are co-extruded geomembranes consisting of outer layers of virgin-grade, linear, low-density polyethylene with an inner core of virgin and select reprocessed resins. The HydraFlex H-Series membranes are stabilized with carbon black and antioxidants designed as an economical solution for near- to-mid-term applications. The premium quality LLDPE contained in the H-Series product line offers project value by providing for ease of welding along with high impact strength and tear resistance.

Raven Industries is committed to developing innovative materials by engineering value-added and sustainable products to meet and exceed the latest industry standards. The company has established a well-known reputation for manufacturing and supplying high-performance flexible films and sheeting to major markets in the United States and abroad.
