What is hydrogenated nitrile used for?
Hydrogenated Nitrile is widely used in automotive and oil industries and maintains excellent resistance to motor oils, sour gas, amine/oil mixtures, oxidized fuels, and lubricating oils.
What is hydrogenated rubber?
Hydrogenated Nitrile Butadiene Rubber, abbreviated as HNBR, is a synthetic rubber material that is used to create industrial sealing for oilfield exploration and processing. It is also used in the manufacture of belts, dynamic and static seals and hoses that are used in the automotive industry.
What is hydrogenated nitrile butadiene?
Hydrogenated Nitrile Butadiene Rubber – HNBR HNBR is made via selective hydrogenation of the NBR butadiene groups which improves the temperature and ozone resistance considerably. HNBR is widely known for its physical strength and retention of properties after long-term exposure to heat, oil, and chemicals.
What is the difference between HNBR and NBR?
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.
Does nitrile rubber melt?
Although acrylonitrile is a type of cyanide, it doesn’t break up into ions once dissolved in water, which gives the type of cyanide used as poison its deadly characteristics. Instead, the material’s molecules dissolve without breaking up, rendering it harmless.
What is Viton rubber used for?
Viton: A Rubber Compound for Fuel and Oil Applications These days, Viton seals, o-rings, and others rubber parts are now used regularly in the automotive, appliance, chemical, and fluid power industries thanks to its natural resistance to both fuel and oil.
Is nitrile rubber conductive?
Why are nitrile gloves less conductive? Gloves made from natural rubber latex are inherently static insulative, holding on to a charge and releasing it in an uncontrolled manner, leading to damage. However, the surface resistance of nitrile gloves is normally on the border of insulative and static dissipative.
What is nitrile made from?
nitrile rubber (NBR), also called nitrile-butadiene rubber, an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. Nitrile rubber is mostly used where high oil resistance is required, as in automotive seals, gaskets, or other items subject to contact with hot oils.
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 is NBR rubber used for?
nitrile rubber (NBR), also called nitrile-butadiene rubber, an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. Its main applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required.
Is nitrile rubber hazardous?
Nitrile rubber is not toxic. Although acrylonitrile is a type of cyanide, it doesn’t break up into ions once dissolved in water, which gives the type of cyanide used as poison its deadly characteristics. Instead, the material’s molecules dissolve without breaking up, rendering it harmless.
Which is better hydrogenated nitrile or hydrogenated butadiene rubber?
The properties of hydrogenated nitrile rubber (HNBR) depend upon the acrylonitrile content and the degree of hydrogenation of the butadiene copolymer. HNBRs have better oil and chemical resistance than nitrile rubbers and can also withstand much higher temperatures.
How is HNBR produced from conventional nitrile rubber?
It can be produced from conventional nitrile rubber by hydrogenation of the unsaturated bonds in the butadiene units of the polymer: The properties of hydrogenated nitrile rubber (HNBR) depend upon the acrylonitrile content and the degree of hydrogenation of the butadiene copolymer.
What kind of rubber does Southbourne rubber use?
Offering heat resistance up to 140°C as well as standing up to adverse environmental conditions, Southbourne Rubber often uses HNBR in the manufacture of rubber seals for gear boxes and rubber gaskets with a long service life. What is Hydrogenated Acrylonitrile Butadiene Nitrile Rubber (HNBR)?
What are the mechanical properties of HNBR polymer?
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. The mechanical properties like tensile and tear strength, elongation, and abrasion resistance are also excellent.
