Seaman Corp. of Wooster, Ohio, has released a new fire-retardant geomembrane, XR-FR, in its XR Geomembranes product line. With the product line’s history of proven performance, a fire-retardant flexible geomembrane has been introduced into the product lineup. The XR-FR product is appropriate for use in secondary containment of aboveground flammable and combustible liquid tanks. It meets the requirements of ULC S668, the Canadian “Standard for Liners Used for Secondary Containment of Aboveground Flammable and Combustible Liquid Tanks.” Class IA secondary containment liners are suitable for use with flammable liquids, flammable liquids containing ethanol or methanol, combustible liquids, and combustible liquids containing up to 5% biodiesel (B5).
When selecting a geomembrane liner, puncture strength, abrasion resistance, flexibility and toughness are important properties to consider. The flexibility of XR-FR allows for improved liner integrity and significantly reduces the number of field seams. The broad range of chemical resistance and physical properties rivals the competition for superior protection against UV and puncture.
There are three grades of XR Geomembranes for containment: XR-5 for broad chemical resistant applications requiring high-strength geomembranes, XR-3 for moderate chemically resistant requirements, XR-PW for potable water contact products and XR-FR for installations requiring extra fire protection.
Seaman Corp.’s track record of successful installations containing a variety of harsh liquids has given it a recognized position of leadership in this specialized field.
