NBR (nitrile butadiene rubber)

.

Among standard seals such as O-rings and radial shaft seals, NBR is the most widely used material.

The reasons for this are good mechanical properties, high abrasion resistance, low gas permeability

and the high resistance to mineral oil based oils and greases.

NBR is a copolymer of butadiene and acrylonitrile.

Depending on the application, the content of acrylonitrile can vary between 18% and 50%.

Low ACN content improves cold fl exibility at the expense of the resistance to oil and fuel.

High ACN content improves the resistance to oil and fuel while reducing the cold fl exibility and increasing compression set.

NBR has good resistance to:

mineral oil-based oils and greases

aliphatic hydrocarbons

vegetable and animal oils and fats

hydraulic oils H, H-L, H-LP

hydraulic fl uids HFA, HFB, HFC

silicone oils and silicone greases

water (max. 80°C)

NBR is not resistant to:

fuels with high aromatic content

aromatic hydrocarbons

chlorinated hydrocarbons

non-polar solvents

hydraulic fl uid HFD

glycol-based brake fl uids

ozone, weathering, ageing, UV resistance
