US’ Seaman has launched a fire-retardant XR geomembrane. 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 Standard for liners used for these applications. Seaman is a world leader of innovative, high performance coated fabrics.

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 per cent biodiesel (B5). When selecting a geomembrane liner, puncture strength, abrasion resistance, flexibility, 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, Seaman said in a press release.

There are three grades of XR Geomembranes for containment: XR-5 for broad chemical resistant applications requiring high-strength membranes; XR-3 for moderate chemical resistant requirements; XR PW for potable water contact products; and XR-FR for installations requiring extra fire protection.

Seaman Corporation’s extensive track record of successful installations containing a variety of harsh liquids has given it a recognised position of leadership in this very specialised field.
