XN90BK00 is a 90 shore A black XNBR compound designed for demanding sealing applications where high hardness, abrasion resistance, and durability are critical. This carboxylated nitrile formulation offers improved compression set resistance and enhanced tear strength compared to standard NBR, making it ideal for O-rings and gaskets used in hydraulic systems, heavy equipment, and high wear environments. It provides reliable resistance to oils, fuels, and many industrial fluids while maintaining performance across a service temperature range of -40°C to 125°C. XN90BK00 meets ASTM D2000 M6BG910 requirements and can be compared to other high durometer XNBR materials when evaluating equivalent solutions for abrasive or dynamic sealing applications.
XNBR, or carboxylated nitrile rubber, is an advanced version of NBR that incorporates carboxyl groups to significantly improve mechanical strength, abrasion resistance, and resistance to tearing. These materials are widely used in O-rings and gaskets where standard nitrile compounds may wear prematurely, particularly in dynamic or high pressure environments. XNBR retains the strong oil and fuel resistance of NBR while offering longer service life and improved performance under mechanical stress. It is commonly used in automotive, oil and gas, and industrial applications where durability and cost effectiveness are key considerations.
