ECO NBR - Acrylonitrile Butadiene Rubber
ECO NBR is an elastomer based on acrylonitrile - butadiene rubber which is used for U-rings, chevron packings, special seals and various components. This material has a good resistance to mineral oils and greases and HFA, HFB and HFC pressure fluids. However, the material is not resistant glycol-based brake fluids, HFD fluids, aromatic fluids (such as benzene), esters, ketones and amines or concentrated acids and bases.
