Description Elast-O-Lion® 101 is a James Walker-formulated hydrogenated acrylonitrile/butadiene (HNBR) synthetic rubber with 36% ACN. It was developed specifically for ED resistance.
Special features
Norsok M-710 qualified for explosive decompression (ED) resistance and sour gas (H2S) ageing.
Excellent ED resistance, making it ideal for high-pressure gas applications.
Offers the excellent oil/fuel resistance of nitrile NBR elastomers.
Outstanding abrasion resistance.
Superior mechanical strength.
Better weatherability and better thermal capability than nitrile NBR.
Elast-O-Lion® 101 is approved and specified by oil producers and equipment manufacturers.
Temperature capability From -25°C (at atmospheric pressure) to +160°C, or +177°C intermittent (-15°F to +320°F, or +350°F intermittent).
