Material characteristicsMaterial characteristics of nitrile
rubber1. Nitrile rubber is a crystalline amorphous
polymer with low adhesive strength,which requires the
addition of a reinforcing agent to have practical value.
Nitrile rubber with a higher mass fraction helps
to improve the strength and wear resistance of vulcanized
rubber, but it will reduce elasticity.2. Oil resistance is a
prominent feature of nitrile rubber, which contains polar nitrile
groups and is resistant to nonpolar or weakly polar mineral oils,
animal and vegetable oils, liquid fuels, and
solvents chemicals have good resistance. The higher the mass
fraction of the nitrile rubber, the better the oil resistance.3.
The heat resistance is superior to NR, SBR, and CR, and can be used
for a long time in hot air at 120ºC.4. Cold resistance and low
temperature resistance are poor, and the higher the nitrile
rubber mass fraction, the poorer the cold resistance.5. The
airtightness is good, second only to IIR in general rubber.6. The
heat-resistant oxidation and photoaging properties are superior to
NR.7. The dielectric properties of nitrile rubber are poor and
belong to the category of semiconductor rubber. Product
