HNBR
Comparable to NBR, it shares the same molecular composition with the addition of hydrogen, which determines its resistance to ozone.
Compared to NBR it has greater resistance to high temperatures. It is massively used in the automotive and air conditioning sectors. It can also significantly improve chemical compatibility by acting on the amount of contained acrylonitrile.
