Hnbr rubber

Hydrogenated nitrile butadiene rubber ( HNBR ) Hydrogenated nitrile butadiene rubber ( HNBR ) is produced by hydrogenation of NBR. Doing so removes the olefinic groups, which are vulnerable to chemical degradation. The nitrile groups are unaffected.

HNBR elastomers offer an excellent range of performance at a cost between nitrile rubber (NBRs) and (per)fluoroelastomers (FMKs). They fill the gap between these two elastomers in many areas of application where resistance to heat and aggressive media are required simultaneously.

The NBR backbone still contains double bonds remaining from the 3-butadiene monomer units.

NBR is a copolymer of ACN and 3-butadiene. Hydrogenated Nitrile Butadiene Rubber ( HNBR ) is characterised by its high strength and property retention after exposure to heat, oil and chemicals. It commonly finds applications in automotive, industrial and other performance demanding applications.

They have rather better oil and chemical resistance than Nitrile Rubber and can withstand much higher temperatures. HNBR rubber compounds perform well in petroleum based oils and fuels, aliphatic hydrocarbons, vegetable oils, silicone oils and greases, ethylene glycol, water and steam to 150°C ( 300°F), and dilute acids, bases and salt solutions to moderate temperatures.

The fiber textile is subjected to dipping treatment before calendering.

Tali variazioni sono più apprezzabili alle alte temperature (150°C). SNOWPLOW RUBBER CUTTING. This product is designed for use as belt wiper or conveyor skirtboard.

Skirtboard is ideal for mounting pa flapping, sealing strips, or general construction and industrial use where abrasion resistance is imperative.

CONTATTI Technical Rubber S. HNBR O-Rings (Hydrogenated Nitrile Rubber seals) HNBR o-rings are produced from the hydrogenation of Nitrile, resulting in varying degrees of saturation of the polymeric chain, along with a range of enhanced physical strength and chemical resistance properties. Hydrogenated Nitrile Rubber ( HNBR ) Hydrogenated Nitrile( HNBR ) is a synthetic polymer that is obtained by saturating the double bonds in nitrile’s butadiene segments with hydrogen, and it is also called HSN(Highly Saturated Nitrile).

Please note: All HNBR material supplied by Eastern Seals is peroxide cured. Description: Hydrogenated Nitrile is the product of the hydrogenation of Nitrile, resulting in varying degrees of saturation of the polymeric chain, along with a range of enhanced physical strength and chemical resistance properties.

Proprietà e utilizzo. Anche se le proprietà fisiche e chimiche variano a seconda della composizione del copolimero, questa forma di gomma sintetica è generalmente resistente a olio, carburanti e altre sostanze chimiche. HNBR also resists new bio-oils (biological oils). Find the lowest price for Hnbr rubber sheet today!

Transformation to HNBR usually takes place at a temperature of 50°C and under bar hydrogen pressure, in polymer solutions containing weight percent rubber. The catalyst is then separated off by filtration or centrifuging Once it has been separated off, it can in principle be reuse although its activity will be reduced. It is a synthetic copolymer of acrylonitrile and butadiene.

HNBR or hydrogenated nitrile rubber is widely used due to its physical strength and retention of properties even after the exposure to heat, oil, and chemicals.

It is ideal for various sealing applications: Zetpol can be used on front cover, intake manifol and oil pan gaskets, as well as drain plug seals and water pump seals. The reactive double bonds are removed from NBR. As a result, the molecule chain does not react as easily to oxygen and is thus significantly more heat resistant than NBR.

In addition, HNBR offers better wear behavior in dynamic applications. The properties of the HNBR rubber depend on the ACN content which ranges between % and % as well as on the degree of saturation. HNBR shows good mechanical properties.

HNBRs have better oil and chemical resistance than nitrile rubbers and can also withstand higher temperatures. High-Performance hydrogenated nitrile rubber ( HNBR ), which has been developed by Zeon Corporation, contains a cure site in the polymer chain.

In this process the molecular “double bonds” in the NBR primary polymer chain undergo a hydrogenation process and therefore the term “hydrogenated nitrile”. Theseproduce a compound with greater tensile strength, improved temperature ranges, significant extrusion and wear protection, along with a broader range of chemical resistance.

HNBR orings are also known as Highly Saturated Nitrile (HSN) o-rings. Le gomme HNBR possono essere utilizzate su un’ampia gamma di temperature (da -40°C a 165°C) con una degradazione minima del composto.
