Highly Saturated Nitrile HNBR O Rings/Hsn O Rings

Highly Saturated Nitrile HNBR O Rings/HSN O RingsHydrogenated nitrile (HNBR)
Walle HNBR is for its range of high performance hydrogenated nitrile elastomers.Chemical properties of HNBR O RING
These materials have the excellent oil and fuel resistance of traditional nitrile (NBR) elastomers with a similar ACN content. In addition they display superior resistance to aggressive fluids such as sour (H2S) crude oil, lubricating oil additives and amine corrosion inhibitors. Fully saturated grades of HNBR have excellent resistance to ozone.Typical operating temperatures for HNBR O RING
-40°C to +160°C continuous, or +170°C intermittent.
Grades are available for continuous operation below -40°C, usually at the expense of the upper temperature limit.Sealing duties
Walle materials have have superior mechanical properties and outstanding wear resistance in dynamic sealing applications. They can often sustain higher service temperatures than traditional nitrile (NBR), such as up to +180°C in oil.Standard range of HNBR O RING
Five ranges are available with various acrylonitrile content from low to ultra-high, and hardnesses of 50-90 IRHD.In addition, Walle 101 and 985 are higly recommended for oilfield duties where a combination of high mechanical strength, rapid gas decompression (RGD) resistance, and chemical resistance is required.
