Daemar’s Range of HNBR Elastomers

Hydrogenated Acrylonitrile Butadiene (HNBR), also known as Highly Saturated Nitrile (HSN) is superior to NBR in low brittle temperature, heat, oil, oil additive and sour oil resistance, and is far more resistant to sour gasoline and ozone than NBR.  HNBR is ideal for industrial products normally made of NBR, and can be used in more severe conditions with much longer service life.


Full line of 70, 80, and 90 Durometer

Daemar’s HNBR o-rings are available in complete range of durometer to cover various applications of different industries.

APPLICATIONS

HNBR elastomers provides an amazing range of performance at a cost between nitrile rubber (NBRs) and (per)fluoroelastomers (FMKs). They fill the gap between these two elastomers in numerous areas of application where there is a need of resistance to heat and aggressive media simultaneously. They are a right choice for applications where resistance to ozone and weathering, industrial lubricants, amine based corrosion inhibitors, sour gases (H2S), and  hot water/steam up to 150°C is needed.

Typical applications include o-rings, hammer union seals and gaskets for use in the oil and gas industry.

HNBR Advantages
    • Excellent media resistance
    • Excellent heat and oxidation stability
    • High mechanical strength
    • Improved wear resistance
    • Good in (ultra-pure) water and steam
    • Temperature range from –50 °C to +160 °C

 

Temperature Range: -50° F to 300° F
Usual Colour: Black
Usual Hardness Range: 70-90 Shore A

Cold Weather Benefits

To keep up with the rising demand of cold weather applications for HNBR, our 80 durometer  HNBR o-rings are temperature rated to -50°C.  We also have HNBR available in 70 and 90 durometer.


Note: HNBR is not recommended for exposure to ketones, esters, ethers, and aromatic fluids.
