HNBR seals
Obtained by hydrogenating nitrile rubber, HNBR seals offer outstanding physical properties. In particular, abrasion resistance, combined with good mechanical properties at elevated temperatures, plus excellent resistance to many chemically aggressive technical oils.
What are HNBR seals used for?
HNBR seals, gaskets and mouldings are recommended for applications requiring good heat, ozone and abrasion resistance, such as automotive components. They are particularly suitable in Motorsport & Specialist Automotive for Engine seals, grommets and gaskets and in the Subsea, Oil & Gas industry for sealing in oil field exploration and processing.
