HN75BK15 is a 75 shore A black HNBR compound engineered for low temperature sealing applications where improved durability and thermal performance are required. This material offers good abrasion resistance, low compression set, and reliable sealing performance in O-rings and gaskets exposed to oils, fuels, and demanding mechanical conditions. Its enhanced formulation maintains flexibility down to -50°C while performing effectively up to 165°C, making it suitable for automotive, oil and gas, and industrial systems. HN75BK15 meets ASTM D2000 6BG814 requirements and can be compared to Parker KA158-70 and N0103-70 when evaluating equivalent low temperature HNBR materials.
HNBR, or hydrogenated nitrile rubber, is an advanced version of NBR that provides improved heat resistance, mechanical strength, and aging performance compared to standard nitrile compounds. These materials are widely used in O-rings and gaskets where exposure to oils, fuels, and moderate temperatures is common, while also offering better low temperature flexibility and durability. HNBR compounds are commonly used in automotive systems, oil and gas equipment, and industrial machinery where a balance of performance and cost effectiveness is required. While more robust than standard NBR, they may still have limitations with strong acids or certain aggressive chemicals, making proper material selection important.
