What temperature can nitrile withstand?
Due to its excellent resistance to petroleum products, and its ability to be compounded for service over a temperature range of -35°C to +120°C (-30°F to +250°F), Nitrile /NBR is the most widely used elastomer in the seal industry today.
What is the difference between NBR and HNBR?
NBR is an abbreviation of nitrile rubber while HNBR is the hydrogenated form of nitrile rubber. The key difference between NBR and HNBR is that NBR is a non-hydrogenated form, whereas HNBR is a hydrogenated form. Moreover, NBR has a comparatively low tensile strength compared to HNBR.
Is HSN and HNBR the same?
HNBR (Hydrogenated Nitrile Butadiene Rubber), also known as Highly Saturated Nitrile (“HSN”), is special class of nitrile rubber (NBR) that has been hydrogenated to increase saturation of the butadiene segment of the carbon polymer backbone.
What is HNBR used for?
HNBR is recommended for applications requiring good heat, ozone and abrasion resistance, such as automotive components. It is 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.
Are HNBR O rings gasoline resistant?
HNBR o-rings are made from hydrogenated nitrile specifically designed to provide superior temperature and fuel resistance compared to traditional NBR materials.
What is HNBR elastomer?
Hydrogenated acrylonitrile butadiene rubber (HNBR) is a unique elastomer. Like NBR, this type of elastomer has excellent resistance to oils and fuels but it also has excellent resistance to many chemicals, heat (steam / hot water) and ozone.
Is HNBR fuel resistant?
HNBR is resistant to mineral oil-based hydraulic fluids, animal and vegetable fats, diesel fuel, ozone, sour gas, dilute acids and bases. HNBR is suitable for high dynamic loads and has a good abrasion resistance. HNBR is suitable for temperatures from -30°C to +150°C (-20°F to +302°F).
Are all green O rings HNBR?
HNBR O-Rings are most commonly in Green or Black, are also avaialable in Yellow and red special compounds.
What are HNBR o-rings made of?
HNBR o-rings are made from hydrogenated nitrile specifically designed to provide superior temperature and fuel resistance compared to traditional NBR materials. HBNR o-rings also feature excellent abrasion, wear, and compression set resistance, making them a reliable o-ring in a wide range of tough applications.
Are HNBR o-rings oil resistant?
HNBR is resistant to mineral oil-based hydraulic fluids, animal and vegetable fats, diesel fuel, ozone, sour gas, dilute acids and bases. HNBR also resists new bio-oils (biological oils). HNBR is suitable for high dynamic loads and has a good abrasion resistance.
Is HNBR oil resistant?
What does HNBR O-ring stand for?
Hydrogenated Nitrile Butadiene Rubber
The Hydrogenated Nitrile Butadiene Rubber (HNBR) O-ring has quickly grown in importance over the last years, due to its excellent cost-performance balance and use in highly demanding applications such as automotive, industrial applications which require high performance.
What is the temperature range of the HNBR O ring?
The HNBR O-ring has a temperature range from -30°C to +150°C (-20°F to +302°F). Obtained by hydrogenating the nitrile copolymer, the HNBR O-ring fills the gap left between NBR, EPDM and FKM elastomers where high temperature conditions require high tensile strength while maintaining excellent resistance to oils and chemicals.
What should the service temperature be for HNBR?
HNBR is classified by ASTM as a DH-type polymer. This classification indicates 150ºC service temperature as well as less than 30% swell in IRM 903 oil. HNBR can be formulated to meet application temperatures ranging between -35°C and 150ºC.
Which is better for heat NBR or HNBR?
HNBRs have better oil and chemical resistance than nitrile rubbers and can also withstand much higher temperatures. Like NBR, this type of elastomer has excellent resistance to oils and fuels but it also has excellent resistance to many chemicals, heat (steam / hot water) and ozone.
What’s the best temperature to use HNBR seals?
HNBR can be formulated to meet application temperatures ranging between -35°C and 150ºC. Seals Eastern is proud to have chosen Zeon Chemical Zetpol® brand of HNBR polymer as the backbone of our HNBR o-rings, seals, and packer elements.
