ECORUBBER 1 (NBR) black
Ecorubber 1 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 to glycol-based brake fluids, HFD fluids, aromatic fluids (such as benzene), esters, ketones and amines or concentrated acids and bases.
ECORUBBER-H (H-NBR) black
Ecorubber-H is a hydrogenated or saturated acrylonitrile-butadiene rubber, which is suitable for applications in aliphatic hydrocarbons like propane or butane and mineral oils and greases (for short times up to 170°C) and also for sulfonated crude oil. Furthermore, it can be used in many diluted acids and bases and salt solutions even at elevated temperatures and in glycol-water mixtures. Ecorubber-H is not compatible with fuels with a high content of aromatic hydrocarbons (premium blend petrol), gasoline?s (petrol / alcohol blends) ketones, esters, ethers and chlorinated hydrocarbons like trichloroethylene and tetrachloroethy-lene.
