of hydrogen gas, in conjunction with a precious metal alyst at a designated temperature and pressure, brings about a selective hydrogenation to produce HNBR. The nitrile groups are unaffected during the process, but the carbon-carbon double bonds in nitrile rubber are converted into more stable single bonds. Different grades can be made by precise control of the proportion of unconverted
7/5/2014· HNBR. HNBR is similar to NBR but has a greater resistance to ozone. HNBR offers improved physical properties and greater abrasion resistance than other polymers. It also has a broad temperature range and great dynamic properties–making it an ideal solution for the oil and gas industry–and it is typically compounded with low amounts of plasticizers to help reduce extraction.

tested are aggressive on the Nitrile and HNBR elastomers. HNBR or Nitrile materials are in almost every mobile air conditioning system. Service Shops or Rebuilders could select a new replacement elastomer to match the alternative refrigerant but there are many existing elastomers in the air conditioning system that might also need replacement. Hoses could also be effected by the aggressive
HNBR delivers resistance to oil, gas and steam that is superior to standard nitrile butadiene rubber (NBR) and other polymers. Medical Gloves, Hoses and belts, Cables, Automotive Seals, Synchronous Belts, etc. Because of the wide appliion of the HNBR, the products are of a wider range.
11/3/2009· "The switch to HNBR is really only for heat resistance, and maybe a little abrasion resistance for the Ford springlock couplers; it is not a chemical compatibility issue." "Compatibility of NBR O-Rings is classed as good with R12, R134a, Mineral oil, POE oil, and PAG oil. The temp range for NBR is …

There are two versions of NBR, hydrogenated nitrile (HNBR) and carboxylated nitrile (XNBR). The hydrogenated version of nitrile, HNBR, is known for its physical strength, increased resistance to oils, industrial chemicals and increases heat resistance. HNBR is widely used in automotive air conditioning units. It is also used in hoses, belts, and seals for the oil field exploration and
6/12/2016· Automotive: As the automotive industry is making ever-stricter demands to improve reliability and performance, new grades of HNBR materials allow an extended service temperature range in dynamic and static seals, hoses and belts. HNBR is on its way to replacing the polychloroprene in automotive timing belts, and they currently account for more than 50% of HNBR use in Europe.
Parker''s hydrogenated nitrile KB163-90 (HNBR) a hydrogenation of nitrile rubber (NBR), has superior mechanical characteristics, particularly high strength, resulting in increased strength and durability. Shore A diamterr of 90 and black in color, . • Heat resistance - Up to 149°C (300°F) with excursions up to 163°C (325°F) • Cold flexibility - Down to approximately -32°C (-25°F
Nitrile butadiene rubber (NBR) is a family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers (1, 2-butadiene and 1, 3-butadiene). It is generally resistant to oil, fuel, and other chemicals (the more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material). Permeability for gasses can be poor depending on the compound.
The use of Zetpol enables the manufacture of rubber parts including seals, hoses and gaskets with excellent functionality at high temperatures. Zetpol is also the ideal choice for oil drilling appliions, because of its resistance to steam and acid as well as crude oil and natural gas.

HNBR is widely known for its physical strength and retention of properties after long-term exposure to heat, oil, and chemicals. Depending on filler selection and loading, HNBR compounds typically have tensile strengths of 20 – 31 MPa when measured at 23°C. Compounding techniques allow for HNBR to be used over a broad temperature range, -40° to 165°C, with minimal degradation over long
HNBR is a hydrogenated version of NBR (nitrile) rubber. NBR is a copolymer of ACN and 1,3-butadiene. The NBR backbone still contains double bonds remaining from the 1,3-butadiene monomer units. These double bonds are also prone to chemical attack, thermal degradation and oxidation. To improve these properties, NBR can be hydrogenated in a alytic hydrogenation process to form HNBR. HNBR is
