Nitrile rubber
, also known as
NBR
,
Buna-N
, and
acrylonitrile butadiene rubber
, is a
synthetic rubber
copolymer
of
acrylonitrile
(ACN) and
butadiene
. Trade names include
Perbunan
,
Nipol
,
Krynac
and
Europrene
.
Nitrile butadiene rubber
(
NBR
) is a family of unsaturated copolymers of
2-propenenitrile
and various butadiene monomers (
1,2-butadiene
and
1,3-butadiene
). Although its physical and chemical properties vary depending on the polymer’s composition of
nitrile
, this form of synthetic rubber is unusual in being generally resistant to oil, fuel, and other chemicals (the more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material).
Due to its excellent resistance to petroleum products, and its ability to be compounded for service over a temperature range of -35°C to +120°C (-30°F to +250°F), Nitrile /NBR is the most widely used elastomer in the seal industry today. Also many military rubber specifications for fuel and oil resistant O-rings require nitrile based compounds.
