Description:

Hydrogenated nirtrile results from the hydrogenation of standard nitrile.HNBR`s main chain is primarily composed of highly saturated hydrocarbons and acrylonitrile( CAN). Thanks to their saturation, the hydrocarbon segments impart heat, chemical, and ozone resistance.

Keep in mind that increased hydrogenation also leads to decreased low temperature elasticity.As with standad nitrile, the CAN content of HNB imparts toughness, as well as fuel and oil resistance.

This ACN content can be modified for specific uses. There are also a few ramaining unsaturated butadiene segments ( typically well under 10% ) to facilitate perocide curing or in some instances, sulfur vulcanization.

Peroxide- cured HNBR has improved thermal properties and will not continue to valcanize like sulfur-cured nitriles.

HNBR is also finding wider use as and alternative to fluoroelastomer rubber (FKM) in shaft seals. Why the switch?

The hardness of the mineral fillers- primarily calcium sulfate (CaSO4) and barium sulfite (BaSO3)-used to improve fluorcarbon`s wear properties can cause grooving of the metal shaft, eventullay providing a leak path that leads to seal failure.

With other materils, carbon black ( Which is not as abrasive as the mineral fillers ) might be substituted, but carbon black is not suffcient to give fluorocarbon good abrasion resistance. On the other hand,HNBR has excellent abrasion resistance, making it a viable alternative to FKM.

HNBR also has better low temperature properties and tear resistance than fluorocarbon.

General temperature range: -25F to 300℉

HNBR performs well in :

 Automotive applications

( as O rings, timing belts, fuel injector seals, fuel hose, shaft seals, diaphagms, and in air conditioning systerms )

 Oil fiels and applications

( as O rings, well-hand seals,drill-bit seals, packers,drill-pipe protectors)

HNBR does not perform well in:

Esters

Ethers

Hydrocarbons ( Chlorinated )

Ketones
