O-RÕNGASNÖÖR D-4,0MM NBR

Kirjeldus

PROPERTIES
Compound Nitrile rubber (N70)

Acrylonitrile-butadiene rubber – NBR
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 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

Application temperature range:
Standard types -30°C to +100°C (short term +120°C)
Special grades possible down to -50°C
